Siamese Twin Songs (or, if you prefer {{Conjoined Twin|s}} Songs, but it doesn't have the same ring) are those which are separate, consecutive tracks on an album where the first one leads into the second as if they were one song. If the first is played without the second, it sounds as if it has been cut off in the middle. If played on the {{radio}}, they are almost always played together. Many times the first track is an EpicInstrumentalOpener.

If downloaded, they generally come as separate files; if ripped from a {{CD}}, they always do. Fortunately, there is software to combine them into one file, at least if they are in either {{MP3}} or open source formats, thus eliminating the annoyance of hearing what sounds like a song ending in the middle when playing songs in random order (shuffle mode).

A very distant cousin to the CliffHanger. Also compare FadingIntoTheNextSong.

Not to be confused with "Siamese Twins Song" from ''Film/BigFish'' or any other songs with the words "Siamese" or "twins" in the title.


* "It's Showtime!" and "Down at [=McDonnellzzz=]" by Music/ElectricSix. They made a video for "[=McDonellzzz=]" but they otherwise don't play one without the other.
* Music/CamperVanBeethoven's "Opi Rides Again" and "Club Med Sucks", sort of: On the original version of ''Telephone Free Landslide Victory'' they were listed as one song called "Opi Rides Again/Club Med Sucks", but the most recent reissue of the album converted them to separate tracks. They're always played together live, too.
* Music/TheWhiteStripes' "Pricky Thorn, But Sweetly Worn" and "St. Andrew (This Battle Is In the Air)".
* Music/GreenDay:
** "Brain Stew" and "Jaded". They were even released as a single together as "Brain Stew/Jaded", shared a music video, and showed up in that sequence on ''[[GreatestHitsAlbum International Superhits]]''.
** On ''Dookie'', the ending breakdown of "Chump" goes straight into the intro to "Longview" with a fading guitar chord and a gradually shifting drumbeat. "Jinx" and "Haushinka" from ''Nimrod'' connect in the same way.
** "Last of the American Girls" and "Murder City" from ''Music/TwentyFirstCenturyBreakdown'' sound incomplete when separated if you've previously heard them together, but they ''can'' work on their own if you like songs that end/start with a random burst of Morse Code.
** "Holiday" and "Boulevard of Broken Dreams" from ''Music/AmericanIdiot'' are also conjoined--the last note of "Holiday" runs through the first several measures of "Boulevard"--but are capable of standing alone. It's more obvious if you're watching the music videos.
* Music/{{Weezer}}'s "Pink Triangle" continues directly into "Falling for You" via a guitar melody and StudioChatter noise.
* Music/SystemOfADown:
** "Thetawaves" and "Roulette" is an odd one. The former is a hard rock song and the latter is an acoustic ballad. Somehow they managed to blend them together to seem like one song.
** This actually applies to all the songs on ''Steal This Album'', as the band had the CD deliberately pressed so there would be no track breaks (so it would seem like a home made CD-R). A particularly good example is "Pictures" into "Highway Song". "Pictures" ends abruptly, and immediately goes into the opening drum beats of "Highway Song", so well that you won't notice unless you know the album well. "Highway Song"'s verse begins at 18 seconds in and is more subdued than its intro.
** Same goes for much of the songs at the beginning of the Toxicity album. Also, Mesmerize album opener "Soldier Side" is treated as an intro to "B.Y.O.B" when played live.
** Also, from "Vicinity Of Obscenity" to "She's Like Heroin", combined by a loud beeping sound. ItMakesSenseInContext.
** Also, Serj Tankian (The lead singer of SOAD) has an example too, from his third solo-album Harakiri, where "Deafening Silence" goes into "Forget Me Knot" (Even to the level that the first song's final note is played in the first split second of the other song).
* Music/TypeONegative's "Summer Breeze" into "Set Me On Fire", on Bloody Kisses. It was originally one song called "Summer Girl", which was based on "Summer Breeze" but had new lyrics written by the band. Summer Breeze's authors Seals And Crofts got an advance copy, and would only allow the band to release the song if they used the original lyrics. The band duly rerecorded the lyrics as requested, though as the second half of the track was entirely original, they just left it as it originally was and indexed it as a separate track called "Set Me On Fire". The original uninterrupted song can be heard on a promo CD.
* Music/{{Coldplay}} used this trope twice on ''Viva la Vida or Death and All His Friends''. First was between "Life in Technicolor" and "Cemeteries of London," but it happens again when "The Escapist" ends the album and flows right back into "Life in Technicolor."
* Music/{{Gorillaz}}'s "Fire Coming Out of a Monkey's Head" is paired with "Don't Get Lost in Heaven," and "Don't Get Lost in Heaven" is paired with "Demon Days." The three flow into each other quite well, forming the climax of the album.
* Music/TheTeaParty did segue on ''Interzone Mantras''. First up is "Cathartik" which plays into "Dust to Gold" which plays into "Requiem."
* Music/SilversunPickups have "There's No Secrets This Year" and "The Royal We."
* Music/TheyMightBeGiants has "Au Contraire" and "Damn Good Times" off ''The Spine''.
* Music/{{Starflyer 59}}'s "I Like Your Photographs" and "...Moves On". Although the former can work as a standalone song (abrupt ending aside), the latter can't, because it's just an extended instrumental coda.
* The Crüxshadows' "Into the Ether" -> "Cassandra" -> "Love and Hatred" are Siamese triplet (or maybe Human Centipede) songs.
* On the Music/{{Evanescence}} album ''Fallen'', the final note of "Tourniquet" fades out into a background tone in the intro of "Imaginary." This does not impede your ability to listen to the songs separately.
* Music/PanicAtTheDisco's first album has "But It's Better If You Do", which leads right into the opening notes of "I Write Sins, Not Tragedies".

* Some recordings of Music/JohannSebastianBach's ''Magnificat in D Major'' split up the parts "Quia respexit humilitatem" and "Omnes generationes" into two distinct tracks despite the fact that the second part is technically part of the first part because the parts are actually supposed to be distinct.
** Recordings of religious oratorios by other composers usually have such Siamese Twin songs for the reason mentioned above.
** Some recordings of J.S. Bach's organ toccatas and fugues or preludes and fugues cut off the last second of the toccata or prelude (which is usually just the reverb from the last notes) and stick it onto the beginning of the fugue, resulting in Siamese Twin songs. Usually this is just a result of poor editing, but with some recordings, the toccata or prelude is immediately followed by the fugue, with only a few fractions of a second of silence in between the two parts.
* Classical music from the late 1700s onwards is full of examples of multi-movement instrumental works (symphonies, concerti, sonatas, etc.) where two or more movements are intended to be played without a break (generally with the word ''attacca'' over the final measure of the earlier movement). Just to give a few examples:
** Music/LudwigVanBeethoven was very fond of this device. Although it features in both Symphony No.5 (in which the third movement leads directly into the fourth) and Symphony No.6 (in which the third, fourth, and fifth movements are played without breaks), he used it even earlier in his Piano Sonata Op.27 No.1, "Quasi una fantasia" - so named because its four movements (a slow rondo, a scherzo, a slow intermezzo, and a lively finale) are played as if the sonata was a fantasia, a single long-form work exploring many different melodic ideas and moods. Other Beethoven examples include his "Emperor" piano concerto (in which the slow movement leads straight into the finale), his violin concerto (in which the slow movement also leads straight into the finale), his String Quartet No.14 (which features seven movements played without breaks), and his Violin Sonata No.10 (in which the slow movement leads directly into the scherzo).
** One of the most striking examples in which it is not the last two movements but the first two movements which lead straight into each other is found in Music/FelixMendelssohn's Violin Concerto. The coda of the first movement builds and builds in energy until finally the full orchestra finishes on a grim E minor chord. However, the first bassoon holds its note after the rest of the orchestra falls silent, leading directly into the slow movement.
** Music/GustavMahler used this device in several of his symphonies. In No.2, the "Resurrection", the third, fourth, and fifth movements are all played without stopping; in No.4, the third movement is in the symphony's nominal home key of G major, but ends on a D major chord to lead straight into the finale (which is also in G major - at first); and in No.5, the celebrated fourth movement Adagietto for strings alone has its lingering final note echoed immediately by a single French horn note which introduces the finale.
** Music/ClaudeDebussy's "Images" for orchestra is divided into three parts: "Gigues," "Ibéria" and "Rondes de printemps," all of which have been performed separately. "Ibéria" is itself divided into three movements, but the slow middle movement, "Les parfums de la nuit," is seamlessly attached to the opening of the final movement "Le matin d'un jour de fête," providing a good reason not to perform the individual movements of "Ibéria" separately.

* Music/{{Pendulum}}:
** "The Island" Part 1 (Dawn) and Part 2 (Dusk).
** Also "Prelude" and "Slam".
* Ayla's "Into The Light" and "Out of the Light". Some MP3 rips combine them into one track.
* Music/{{Kraftwerk}}:
** ''Music/{{Autobahn}}'' has "Kometenmelodie 1 & 2".
** ''Music/TransEuropeExpress'' has "Trans Europe Express" and "Metal on Metal" on the English version.[[note]]The original German version and the international remaster have the bridge between the two as a third.[[/note]]
** ''Computerworld'' has "Numbers" into "Computerworld 2".
** ''Electric Cafe'' has "Boing Boom Tschak" into "Techno Pop".
* Cygnus X's "Kinderlied Part 1" and "Kinderlied Part 2" are seperate tracks on the original release of ''Hypermetrical'', but combined into one on the remastered version.
* Juno Reactor: "Rotorblade"->"Mars", "Nitrogen Part 1"->Nitrogen Part 2", and "Conquistador I"->"Conquistador II".
* Music/{{BT}}, in addition to regularly using FadingIntoTheNextSong, has several examples of this: "Quark"->"Tripping the Light Fantastic", "Embracing the Future"->"Deeper Sunshine", "Loving You More (Garden of Ima Dub)"->"Loving You More (Final Spiritual Journey)", "Blue Skies (Radio Edit)"->"Blue Skies (Delphinium Days Mix)", "Sasha's Voyage of Ima"->"Divinity", "Solar Plexus"->"Nectar", and "Remember"->"Love, Peace, and Grease" (which had separate single releases).
* Music/{{Autechre}}'s ''Quaristice'' has a Siamese ''quintet'' over the tracks [=Fol3=]->[=fwzE=]->90101-5l-l->bnc Castl->Theswere, as well as the straight examples IO->[=plyPhon=], Perlence->[=SonDEremawe=], and Steels->Tankakern. Also, Eutow->C/Pach on ''Tri Repetae'' and Pro Radii->Augmatic Disport on ''Untilted''.
* The album version of "Since I Left You" by Music/TheAvalanches goes straight into "Stay Another Season" after the song ends, even keeping the same drumloop and bringing back the titular vocal sample of the former song. "Etoh" and "Summer Crane" also connect in similar ways.
** Their long-awaited second album ''Wildflower'' has several examples of this as well, most notably the opener, with "The Leaves Were Falling" -> "Because I'm Me" -> the album version of "Frankie Sinatra" -> "Subways," as well as the three-song psychedelic trip of "Park Music" -> "Livin' Underwater (Is Something Wild)" -> "The Wozard of Iz."
* Cylab's "Unparallel Universe->c21d18no3".
* Covenant's "Slow Motion" and "Tabula Rasa".
* Music/{{Anamanaguchi}} "Interlude (Total Tea Time)" and "Meow" on their "Endless Fantasy" album.
* Armin van Buuren has "Prodemium"->"Precious" on ''76'', "Hymne"->"Sail" on ''10 Years'', "Desiderium 207"->"Mirage" on ''Mirage'', and "In Ten Years from Now"->"Last Stop Before Heaven" on ''Intense''.
* Music/VNVNation's ''Transnational'' begins with the EpicInstrumentalOpener "Generator", which leads into "Everything".
* [[Music/MindInABox THYX]]'s "The Endless Journey" and "Network of Light".
* Music/{{Underworld}} has "Crocodile"->"Beautiful Burnout" on ''Oblivion With Bells''.

* Music/FrankZappa's album ''Music/{{Apostrophe}}'' has ''four'' linked songs: "Don't Eat The Yellow Snow" leads into "Nanook Rubs It", which leads into "St. Alphonzo's Pancake Breakfast", which finally leads into "Father O'Blivion".
* Music/AfroCeltSoundSystem has several. From ''Sound Magic'', there's "Dark Moon, High Tide" and "Whirl-y-Reel 2"--the instrumental motif from the former song is repeated at the beginning of the latter. ''Release'' has "Urban Aire", which is an ambient introduction for "Big Cats". Similarly, from ''Seed'', "Rise" is an ambient introduction for "Rise Above It".
* Music/{{Swans}}' "Damn You to Hell" and "I'll Swallow You" from the B-side to the "New Mind"single, which were later appended to the ''Children of God'' reissue as a single track.
** This became a major component of their post-reformation live performances, to the point that the first half of the title track to ''The Glowing Man'' is a rearranged reprise of "Bring the Sun" from their previous album, ''To Be Kind'', to reflect its development from the latter song. [[EpicRocking The reprise alone is over fifteen minutes long.]]

[[folder:Fan Work]]
* When Music/TheMegas came out with ''History Repeating: Blue'', the title song was split into two parts, the first part being an introduction and the second being a remix of ''VideoGame/MegaMan3'''s ever-famous Title Theme.
* Music/SteamPoweredGiraffe's ''The 2¢ Show'' has two pairs of these: "Prelude to a Dream"/"Make Believe" and "The Ballad of Lily"/"Airheart".

* Music/SimonAndGarfunkel with "Old Friends"/"Bookends". In fact, both songs were put together as one track when released as the b-side of the "Mrs. Robinson" single.

* Superdrag's "Slot Machine" and "Phaser".
* Music/BonIver's "Creature Fear" and Team," as well as "Lisbon OH" and "Beth/Rest."
* Rich Aucoin's ''We're All Dying to Live'' is almost an entire album of these, filled with short instrumental tracks that serve primarily as extended intros to the next full song. Of particular note are:
** "1929-1971" and "Watching, Wishing, Waiting", which had formed a single track called "Superman" on the previously released ''Public Publication EP''.
** "Undead Pt. 1 - Estrangement" and "Undead Pt. 2 - Reconciliation", the only set of Siamese Twin Songs on the album that both have unique lyrics.
** "The Little Creatures Know"/"It"/"The Greatest Secret in the World", where the primary song, "It", is given both an extended intro and outro.

* Psyborg Corp's "Lullaby (Blessed By Plutonium)->Technocracy'', the former of which is also the [[EpicInstrumentalOpener album's opener]]. Likewise, their second album opens with "Millennia Frost->Polaris".
* Interface's ''The Perfect World'' has three Siamese twin pairs: "Ignition->It Begins Today", "In Fidelity->Mirror, Mirror", and "Square One->Back To The Beginning".
* Music/NineInchNails has many examples of these on their albums, which often have tracks running together or one song fading in while another is ending, although most of them are separated on the radio and in concert. For instance, "Head Like a Hole" segues into "Terrible Lie" on ''Pretty Hate Machine'', but the two are almost never played together anywhere else (in fact, most NIN shows put "Terrible Lie" near the beginning of the show and "Head Like a Hole" at the end). A straight example is "The Frail" and "The Wretched". The two play back-to-back on ''The Fragile'' and are almost always played together live. They sometimes play "The Frail" without "The Wretched" (usually as an intro to another song), but they never play "The Wretched" by itself.
* Music/{{KMFDM}} has "Brute"->"Trust", "Megalomaniac"->"Stray Bullet", "Mercy"->"Torture", "Me & My Gun"->"Take 'em Out", et al.
* "Fetus" and "Little Death" by Music/{{WASP}}.

* Music/JagaJazzist: "Day" and "Another Day" from ''The Styx'' are sonically distinct, but the last echoing note of "Day" is audible as "Another Day" begins, and "Another Day" ends by reprising the main motif from "Day".

* Music/JudasPriest:
** "The Hellion" and "Electric Eye" on ''Screaming for Vengeance''.
** "Dreamer Deceiver" and "Deceiver" from ''Sad Wings Of Destiny''. Most online radio stations usually just play the latter, but still plays the coda, which is a reprise of the first song.
* Music/DiabloSwingOrchestra's "How to Organize a Lynch Mob" and "Black Box Messiah". The former song is a brief cello solo which works better as an introduction than as a standalone song, and it gets briefly reprised at the end of the latter song.
* Music/{{Savatage}} "Somewhere in Time / Alone You Breathe" from their ''Wake of Magellan'' album.
* Several songs on Music/{{Korn}}'s ''Life Is Peachy''. They even used to play the opening tracks "Twist" and "Chi" (the former lasting less than a minute) together live (though they've started playing "Twist" on its own life in later years).
* Music/{{Tool}} has "Parabol" and "Parabola". Tracks 6 & 7 on the album, directly lead into one another with no silence. Even the video uses both songs.
* Music/BlackSabbath:
** "Behind the Wall Of Sleep" and "N.I.B."
** "Embryo" and "Orchid" are instrumentals that precede "Children of the Grave" and "Lord Of This World." On CD releases they're included as separate tracks. The band had many other examples, such as "Luke's Wall," "Jack the Stripper," "A Bit of Finger," "The Straightener" and "Death Mask." However, these were just subtitles tacked onto songs with longer instrumental sections in an attempt to invoke this trop and make it seem like the albums had more songs.

[[folder:New Wave]]
* Cyndi Lauper's "He's So Unusual" and "Yeah Yeah."
* Music/{{INXS}} "Need You Tonight" not only segues into "Mediate" (a.k.a. "Meditate" on some pressings) on the original album, the 12" single, some greatest hits comps (though not all) and concert performances (at-least up to 1997), but they even had a joint music video.
* Music/TearsForFears:
** On the album ''Songs From the Big Chair'', the sixth track, "Broken", segues directly into the seventh track, "Head Over Heels", which itself segues directly into a reprise of "Broken". The band had previously released "Broken" as the B-Side to Pale Shelter, and used to play it live to beef up their short set. When they added the new song "Head Over Heels" they played it as a medley with Broken, and liked it so much they recorded this for the album.
** ''The Seeds Of Love'' also has "Swords And Knives", "Year Of The Knife" and "Famous Last Words" fade into each other, an effect which isn't done elsewhere on the album. They are linked lyrically in places - "Year Of The Knife" mentions both 'knives' and 'famous final words' tying it in with the other two.
* Music/TheCars have "Double Life"->"Shoo Be Doo"->"Candy-O" (''Candy-O'') and "Moving In Stereo"->"All Mixed Up" (''The Cars'').
* Music/{{Sparks}} has "Propaganda"/"At Home, At Work, At Play", which were written separately but found to work perfectly together.

* From the ''WesternAnimation/SouthPark'' Christmas Album, "O Tannenbaum" (sung by UsefulNotes/AdolfHitler and "Christmastime in Hell" (with vocals led by {{Satan}}). (Though since "O Tannenbaum" and its English translation "O Christmas Tree" have been around much longer than ''South Park'', it was not "born" a Siamese Twin and this example might be better described as a FrankensteinsMonster or [[Film/TheHumanCentipede Human Centipede]] song).
* On many soundtracks for ''Film/TheWizardOfOz'', most of the Munchkinland sequence is present, but cut into many smaller tracks (each less than a minute long), split by main singer. The tracks on one CD are "Come out, Come out" (Glinda), "It Really Was No Miracle" (Dorothy), "We Thank You Very Sweetly" (random Munchkins and Glinda), "Ding-Dong! The Witch is Dead" (Chorus), "As Mayor of the Munchkin City" (Mayor), "As Coroner, I Must Aver" (Coroner), "Ding-Dong! The Witch is Dead (Reprise)" (Chorus), "The Lullaby League" (Girls), "The Lollipop Guild" (Boys), and "We Welcome You To Munchkinland" (Chorus). Combined togeher it's only six minutes, so maybe a split just before "Ding-Dong! The Witch is Dead" is justified as there's the closest thing to a break at that point, but that's it.
* Most of ''VideoGame/MedalOfHonor: Frontline'''s OST consists of suites running across two or more tracks, namely "Border Town->U-4902" (although they play in opposite order in-game), "Kleveburg->Manor House Rally->The Halftrack Chase" (again, in-game, "Halftrack" is heard before "Manor House"), "Nijmegen Bridge->Rowhouses", "Emmerich Station->Thuringer Wald Express->Sturmgeist's Armored Train", and "Approaching The Tarmac->Clipping Their Wings".
* ''VideoGame/ProfessorLaytonVsAceAttorney'' features remixes of songs from the first ''VisualNovel/PhoenixWrightAceAttorney'' game exclusive to the first case. In the soundtrack, these songs are arranged so one flows directly into the next to create what is referred to as the "English Court Suite". The order of the songs is as follows: "Courtroom Lounge", "Court Begins", "Logic and Trick", "Suspense", "Cross Examination ~ Moderato", "Objection!", "Cross Examination ~ Allegro", "Confess the Truth", "Cornered", and "Won the Case".
* ''{{VideoGame/Fez}}'' has "Sync" and "Glitch".

* Katzenjammer's "A Kiss Before You Go" and "I Will Dance (When I Walk Away)".
* Music/{{Madonna}}:
** "Dear Jessie" and "Oh Father" from ''Music/LikeAPrayer''. Interestingly, both were released as singles, but in the opposite at which they play.
** "Holiday" and "Everybody", both from Madonna's debut ''[[Music/MadonnaAlbum Madonna]]'', both about singing and partying and talking about "leaving troubles behind".
* "Show Me Love" and "30 Minutes" by [[Music/{{tatu}} t.A.T.u.]] - the ''Mama, Papa, forgive me'' part at the end of "Show Me Love" is sometimes mistaken as the beginning of the song "30 Minutes".
* The Fifth Dimension's cover of "Aquarius" (the opening number of ''{{Theatre/Hair}}'') combined it with "Let The Sun Shine In" (the final chorus of "The Flesh Failures", the closing number).

[[folder:Prog Rock]]
* Music/PinkFloyd's ''Music/TheWall'' does this with "Outside the Wall" [[HereWeGoAgain and]] "In The Flesh?". While it's common for this to happen on a RockOpera ConceptAlbum, this example sees the ''end'' of the album segue into the ''beginning''.
-->"Isn't this where...we came in?"
** This also occurs with "The Happiest Days of Our Lives" and "Another Brick in the Wall, Part 2".
** "Brain Damage" and "Eclipse" off ''Music/TheDarkSideOfTheMoon'' are so inseparable that they're often collectively [[RefrainFromAssuming mistaken]] for the title track of the album. There is no title track for that album.
** "Young Lust" is only rarely played on radio without its slow-paced lead-in, "Empty Spaces", and "Empty Spaces" is never played on its own.
*** However, it was not meant to be that way. "Empty Spaces" was originally going to be a reprise of a longer version of that same song, "What Shall We Do Now?"[[note]]Though it's still present in the film version[[/note]], and "Young Lust" was originally going to be a song in its own right.
** Considering how many Music/PinkFloyd songs [[FadingIntoTheNextSong Fade into the Next Song]], it's surprising that this doesn't happen more often.
* IQ's "Leap of Faith" and "Came Down", such that it seems surreal to listen to one without the other.
* Rishloo's "Turning Sheep Into Goats" and "Systematomatic".
* Music/DreamTheater:
** "The Mirror" and "Lie."
** Also "Overture 1928" and "Strange Deja Vu" are frequently played together, like most songs from Metropolis, Pt. 2.
** Often subverted by "The Dance of Eternity" and "One Last Time". The first note of "One Last Time" resolves "The Dance of Eternity", but "Dance of Eternity" is often played alone, leaving the end hanging.
** While "Six Degrees of Inner Turbulence" is a single suite, "War Inside My Head" and "The Test That Stumped Them All" are usually played together.
** While also an example of BookEnds, if you have Octivarium on disc-repeat, the end of the last song on the disc plays into the first song on the disc. The song even mentions "the story ends where it begins."
* The Strawbs' "The River" and "Down by the Sea". While easily separable, they are presented this way on the album[[note]](''Bursting at the Seams'')[[/note]], and usually performed this way live. Ironically, they originally appeared on vinyl pressings in reverse order, for fear that the heavy bass on "Down By the Sea" would cause needles to jump off the groove. (Near the end of a side the soundwaves encoded on the groove are closer together due to the smaller circumference).
* Music/TheAlanParsonsProject's "Sirius" and "Eye in the Sky". Also "Nucleus" and "Day After Day (The Show Must Go On)"; those two were included in that fashion in the "Laseruim" show.
* Music/{{Rush}} "Overture" and "The Temples of Syrinx" from ''2112''. While all 7 tracks that make up the 2112 suite are strung together (and are often recorded as a single track onto a CD rather than as separate parts) the "Overture" and "The Temples of Syrinx" are almost ALWAYS played together on the radio and in concert.
* ProgressiveRock supergroup UK have, from their debut SelfTitledAlbum, "In The Dead Of Night"->"By The Light Of Day"->"Presto Vivace And Reprise" starting side one, and "Alaska"->"Time To Kill" starting side two.
* Music/{{Genesis}} have "Unquiet Slumbers For The Sleepers..." -> "...In That Quiet Earth" -> "Afterglow" from ''Wind And Wuthering'', and "The Cinema Show" -> "Aisle Of Plenty" on ''Selling England By The Pound''. "Fly on a Windshield" and "Broadway Melody of 1974" from ''Music/TheLambLiesDownOnBroadway'' also qualify, although ''every single CD release'' has mis-indexed them to make "Broadway Melody" seem like a song snippet (it's intended to start at the line "Echoes of the Broadway Everglades"). Actually, most of the first side of ''The Lamb'' and quite a few other songs on the other three sides could be considered to qualify for this trope, although just as often the band uses FadingIntoTheNextSong.
* Music/{{Hawkwind}} several times, notably "Automotion"/"25 Years", and "Assault and Battery"/"The Golden Void".
* Music/EmersonLakeAndPalmer:
** On CD releases of ''Tarkus'', the titular suite is always presented as [[EpicRocking one long track]].
** ''Trilogy'': "The Endless Enigma, Part 1"->"Fugue"->"The Endless Enigma, Part 2"

* Music/SydBarrett managed one with "Waving My Arms In The Air/I Never Lied To You".
* Music/TheDoors with "Peace Frog" and "Blue Sunday".

* A rather large number of song transitions by Music/{{Crass}} use either this or FadingIntoTheNextSong; they were particularly fond of using guitar feedback to connect two songs. This reached a fever pitch on ''Yes Sir, I Will'', where all the tracks were considered part of one lengthy composition that took up the entire album (a forty-three-minute running time).
* Their friends in Flux of Pink Indians did something similar with all three of their albums. ''Uncarved Block'' uses mostly FadingIntoTheNextSong instead, but their first two albums use this extensively and mostly have gaps only for LP side breaks.

* Music/ChildishGambino's "All the Shine" and "Letter Home" follow each other on the album, and feature the same riff. "Letter Home" is short enough that it probably qualifies more as a coda to "All the Shine" than as an actual song.
* Music/KanyeWest's "Lost in the World" and "Who Will Survive in America" from ''Music/MyBeautifulDarkTwistedFantasy''.
* "Remember Me" and "I'm Back" from Music/{{Eminem}}'s Marshall Mathers LP.

* Music/LedZeppelin's "Heartbreaker" and "Living Loving Maid (She's Just a Woman)" from ''Music/LedZeppelinII''.
** Also "Friends" and "Celebration Day".
** "The Song Remains the Same" and "Rain Song". Unlike the above two examples, this pairing carried over into their concerts for a few tours, with Jimmy using his doubleneck to play the 12-string and alternatively-tuned six-string songs back-to-back.
* Stevie Wright's [[ "Evie", parts I, II and III]], would be examples of Siamese Triplet Songs.
* Music/{{ACDC}}'s "Big Balls" and "Rocker", though they may have been separated some time after birth.
* Music/TheBeatles:
** ''Music/SgtPeppersLonelyHeartsClubBand'' has both "Sgt. Pepper's Lonely Hearts Club Band" and its reprise with "With a Little Help From My Friends" and "A Day In The Life", respectively.
** Also, the ''Music/AbbeyRoad'' medley, with "You Never Give Me Your Money", "Sun King", "Mean Mr. Mustard", "Polythene Pam", "She Came In Through the Bathroom Window", "Golden Slumbers", "Carry That Weight", and "The End" being a Siamese ''octet''. (While "Her Majesty" is a ninth sibling on whom separation surgery was performed... not ''quite'' successfully.)
* Music/{{Queen}}:
** "We Will Rock You" and "We Are The Champions", although they were separate songs on the single, opposite the album order on ''Music/NewsOfTheWorld''. Though both are definitely complete songs on their own, radio [=DJs=] (and listeners) nonetheless got accustomed to playing them together.
** A straighter example would be the Siamese Triplet Songs "Tenement Funster", "Flick of the Wrist", and "Lily of the Valley".
** "Death On Two Legs", "Lazing On A Sunday Afternoon", and "I'm In Love With My Car" from ''Music/ANightAtTheOpera''.
** "Fat Bottomed Girls" and "Bicycle Race" could also count, especially with the latter song mentioning that "fat bottomed girls, they'll be riding today"
* Music/ZZTop's "Waitin' for the Bus" and "Jesus Just Left Chicago".
* Music/VanHalen:
** "Eruption" and their version of "You Really Got Me." It's a bit jarring when ''[[GreatestHitsAlbum The Best of Both Worlds]]'' separates the two songs.
** ''Diver Down'' has two (which are even combined in ''VideoGame/GuitarHero: Van Halen''), "[[{{Instrumentals}} Intruder]]"/"[[CoverVersion (Oh) Pretty Woman]]" and "Little Guitars" and its acoustic intro.
* Music/CreedenceClearwaterRevival's "Poorboy Shuffle" and "Feelin' Blue."
* Pure Prairie League's "Falling In and Out of Love" and "Amie" on their Bustin' Out album.
* Almost all of Music/BlueOysterCult's Secret Treaties album does this, with "Career of Evil" leading into "Subhuman" leading into "Dominance and Submission" leading into "ME 262." Then after the side break, "Cagey Cretins" stands on its own, but "Harvester of Eyes" leads into "Flaming Telepaths," which has {{No Ending}}, leading into "Astronomy" which starts without any gap after Telepaths' sudden stop.[[note]]Best heard on the original vinyl. For some reason, the tape and CD releases butcher the effect by putting the tracks in the wrong running order. Something is definitely lost.[[/note]]
* The Kings' "This Beat Goes On" and "Switchin' To Glide".
* Music/{{Journey}}'s "Feeling That Way" into "Anytime".
* Sometimes averted on the radio, but Santana's "Black Magic Woman/Gypsy Queen" and "Oye Como Va" have faithfully retained their Siamese Twin status in concert and on compilations (sometimes reversed in the case of the latter).
* Music/TheMoodyBlues:
** "The Afternoon: Tuesday Afternoon (Forever?)", "Sunset: The Sunset", and "Evening: Time to Get Away" and "Twilight Time". These sets of two songs couldn't live without their counterparts, often get live radio play together, and might even argue as one, four long track as a whole. You could also count "Twilight Time" leading into "The Night: Nights In White Satin", if the last weren't so famous already.
** Again, the same band also did this for nearly the entire Side B of ''To Our Children's Children's Children''. Four songs, "Gypsy", "Eternity Road", "Candle of Light", and "Sun Is Still Shining" all transition into one another, though the outtakes on the remastered version show that they were originally separate. The same thing happened with ''A Question of Balance''[='=]s "Dawning is the Day" and "Minstrel's Song".
* Music/{{Styx}} "Prelude 12" into "Suite Madame Blue" on ''Equinox.''
** This also occurs on ''Paradise Theatre'' with "A.D. 1928" into "Rockin' the Paradise".
* Music/EltonJohn's "Funeral for a Friend/Love Lies Bleeding" which [[EpicInstrumentalOpener kicks off]] his ''Goodbye Yellow Brick Road'' album. The CD version doesn't separate them and instead has it as one 11-minute-plus track.
* Music/{{Area11}} do this with "Vectors" and "Euphemia" in their debut album, ''All the Lights in the Sky''.
* Music/DavidBowie has, from ''Diamond Dogs'', "Sweet Thing" lead into "Candidate", which then leads into a reprise of "Sweet Thing. On ''"Heroes"'', "Sense of Doubt", "Moss Garden" and "Neuköln" form a suite towards the end.
* Music/{{Badfinger}} have "Money" -> "Flying" from ''Straight Up".
* Sixx:A.M. had a few instances of this on "The Heroin Diaries Soundtrack". Most notably, the second track, "Van Nuys", just feels wrong without Nikki Sixx's monologue in "Xmas In Hell", more so since the music, quiet as it is, actually leads from "Xmas In Hell" into "Van Nuys". Likewise, "Girl With Golden Eyes", "Courtesy Call" and "Permission" just don't have the same effect when you don't hear them right after eachother in that order. They don't sound wrong or anything, they just become far less powerful. Heck, everything between "Interlude" and "Life After Death" should be heard in the correct order, because they're written specifically to be played in that order without interruptions, unlike the first half (Van Nuys, Life Is Beautiful, Pray For Me and Accidents Can Happen are less dependent on eachother).
* The Guess Who have "No Sugar Tonight" and "New Mother Nature".
* Sirius Satellite Radio stations such as "Classic Vinyl" would often play several album cuts that flowed into one another back-to-back, such as Music/PinkFloyd's "Speak To Me/Breathe/On the Run", {{Music/Aerosmith}}'s "Train Kept A-Rollin'/Seasons of Wither", and Music/TheCars's "Bye, Bye Love/Moving In Stereo".
* Inverted by Music/FleetwoodMac: "Oh Well" is supposed to be [[EpicRocking a single 9-minute track]], but the instrumental Part 2 is rarely heard.
* Little Richard specifically wrote "Hey-Hey-Hey-Hey" to be performed as a medley with "Kansas City".
* Music/PattiSmith's "Babelogue" and "Rock 'n' Roll Nigger".
* Music/TheRadiatorsUS:
** "Nightmare on the Misery Train" into the [[Music/GeorgeClinton Funkadelics']] "Take Your Dead Ass Home" from their ''Bucket of Fish'' album.
** A siamese ''triplet'' with "Lucinda" into "The Theme from Film/TheMagnificentSeven" into a cover of Music/TheMeters' "Cissy Strut" from ''Live at the Great American Music Hall''.
* Music/BobSeger's live album ''Live Bullet'' paired "Travelin' Man" and "Beautiful Loser" this way.

* Nearly every song on Music/MarvinGaye's ''Music/WhatsGoingOn'' does this. The title track is an exception, as is the gap between vinyl sides. In addition to the title track, "Mercy Mercy Me (The Ecology)" and "Inner City Blues (Make Me Wanna Holler)" managed to get significant amounts of airplay because they ended their respective vinyl sides.

* Music/SoftCell's cover of "Tainted Love" segues into a cover of The Supremes' "Where Did Our Love Go?", although in this case the two are part of the same track.
* Vicious Pink's "[[EpicInstrumentalOpener 8:15 to Nowhere]]" and "[[JerryLeeLewis Great Balls of Fire]]". The former song was also released as a separate single.

* ''Theatre/{{Seussical}}'' features the songs "Alone in the Universe (Reprise)" and "Solla Sollew." The first is only a minute long and acts as a prelude for the second. Furthermore, the track break is put in the ''middle'' of a rising transition note. Five seconds later would've made the jump much less jarring.
* ''Theatre/NextToNormal'' does this with "You Don't Know" into "I Am The One", as well as "Why Stay/A Promise" into "I'm Alive (Reprise)" into "The Break".
* ''Music/TheSilentCity'' has two examples. The first is between "It's the Start/Overture" and "Commercial (Do It Anyway)," where the first song leaves you hanging for the conclusive note until the beginning of the next. The second is between "Set a Fire" and "The Riot," where the drum beat that leads into the second song starts at the ending of the first.
* In the ''Theatre/{{Spamalot}}'' soundtrack, "Come With Me" leads directly into the "Laker Girls Cheer".
* The Broadway cast recording for ''Theatre/{{Matilda}}'' divides the [[EpicRocking 9 1/2 minute long]] opening number "Miracle" into three tracks. Later, "Chalk Writing" segues to "Revolting Children". The London cast album has the Entr'acte lead into "When I Grow Up".
* In the revised stage musical of ''Disney/TheLittleMermaid'', Ariel's opening number "The World Above" segues directly to "Fathoms Below" (they were separate songs in the Broadway production and on its cast album), and at the end, "If Only (Reprise)" leads into the [[TriumphantReprise final reprise]] of "Part of Your World".
* The rock musical adaptation of ''Music/AmericanIdiot'' does this in spades; "Favorite Son" > "Are We the Waiting" > "St. Jimmy" and "Last of the American Girls" > "Last Night on Earth" are the most notable examples.

[[folder:Visual Kei]]
* Music/{{D}}'s "Hikari no niwa" is the intro to "Namonaki mori no yumegatari"--they even share [[ the same music video]]. One could be forgiven for listening to the album version of the latter and thinking "wait, what happened to the acoustic intro?"
