* Pat Boone's 1997 album, ''In A Metal Mood: No More Mr. Nice Guy'' was completely composed of covers of heavy metal songs, as opposed to his usual fare of R&B, country, and gospel (though they were still done in his milquetoast Big Band/Lounge-style, of course). The CD cover featured the normally clean-cut Boone in leather and chains, an outfit he would also wear at the 1997 American Music Awards. He looked ridiculous, but it didn't do him any favors with the MoralGuardians that make up his primary demographic, who thought he was being serious.
** [[http://www.allmusic.com/album/r246706/review This review]] proves that, amazingly, even some critics didn't get that ''it was a joke''.
* The Colors Album by Between The Buried and Me (Can't say anything about the other albums) has this in each song. For example, Ants of The Sky has polka, PinkFloyd-esque guitar solo, thrashing a-la Metaliica and Megadeth, and intense speed-metal screaming, melodic sections that would make JoeSatriani and Music/DreamTheater proud, and thudding doom-metal sections. ''In a single song.'' The thing is that the styles switch nearly immediately, and doesn't sound bad.
* Almost every single Music/{{Beck}} album does this. There's [[GenreRoulette country, hip-hop, funk, folk, anti-folk, rock, metal, rap, contemporary, balladry, pop, disco, jazz]]... What with this being Beck, sometimes half of those are in the [[NeoclassicalPunkZydecoRockabilly same song]].
* Neil Young put out three such albums in a row, much to the consternation of his label (Geffen famously tried to sue him for delivering "unrepresentative material"): First there was the heavily synth-filled ''Trans'', then TheFifties rockabilly throwback of ''Everybody's Rockin''', and finally the country album ''Old Ways''.
* The first eleven songs on the [[RemedyDrive RemedyDrive]] album ''Magnify'' are all pretty standard rock (and the occasional bass solo). The last one, "Smile Upon Me", is acapella three-part harmony.
* By 1993, [[{{REM}} R.E.M.]] had 2 massively successful albums with ''Out of Time'' (Shiny Happy People, Losing My Religion), and ''Automatic for the People'' (Everybody Hurts, Man on the Moon). Both albums, especially the latter, were relatively slow, emotional albums, with string and acoustic instruments everywhere. In 1994, however, they released ''Monster'', with loud, grunge-y, distorted guitar on nearly every single track [[note]]The lone exception was "Tongue", a piano-based ballad, albeit one with a very brief distorted guitar solo... And even that song sounded pretty different due to Michael Stipe singing most of it in a nearly-unrecognizable falsetto[[/note]].
** Incidentally, those two prior albums fit the trope as well, as the band's major label contract was triggered by the success of the 1987 album ''Document'' (It's the End of the World As We Know It, The One I Love), which consisted almost entirely of songs that were, by the band's standards, real rockers. The interceding album, 1989's ''Green'', seemed to be following that pattern, with just a few acoustic songs between upbeat rock songs like "Stand," "Orange Crush," and "Pop Song '89."
* [[{{Keane}} Keane's]] first 2 albums were straight piano rock, very similar to Coldplay or Ben Folds. Their third album, ''Perfect Symmetry'', had a very 80's inspired sound featuring heavy synths, prominent basslines, a wide array of instruments, and, for the first time since well before the release of ''Hopes and Fears'', guitars. Their next album, ''Strangeland'', was straight-up piano rock in a similar style to ''Hopes and Fears''.
* "Golden Brown", a sincere, harpsichord-led baroque pop single by punk band The Stranglers. It is their most acclaimed, popular and best selling song.
** This goes for their entire career from that moment on, as they shifted to moody baroque pop, and later to AOR.
* "Revolution 9" by Music/TheBeatles isn't like ''anything'' else out there.
** Minor example: ''A Day in the Life'' is a soft, sad-esque song about a guy who reads in the newspaper the story of an unlucky man, the war, a car crash, a suicide, etc. By the middle of the song, it starts an upbeat ballad about going late for work.
* HardcorePunk band The Bronx, after releasing three self-titled albums, released an album of mariachi music under the name "Mariachi El Bronx" in 2009, followed by another in 2011. Both albums are critically acclaimed.
* {{Outkast}} did this twice in a row. 2003's ''Speakerboxxx/The Love Below'' was a double album with each disc being a solo effort from one half of the duo: Big Boi's ''Speakerboxxx'' a conventional hip-hop album and Andre3000's ''The Love Below'' being more experimental. In 2006 they released ''Idlewild'', the soundtrack to their 20's-era musical, meaning most songs were more of a jazz style, plus there were only a couple songs that Big Boi and Andre performed together. To recap, Outkast has not released a standard album since 2000's ''Stankonia''.
* While Music/ToriAmos' sound evolves with every album, 1999's ''Strange Little Girls'' is a CoverAlbum of songs originally performed by men, exploring what it means to be a man [[TheCoverChangesTheGender from a woman's perspective]].
* Bob Dylan's been known to do this from time to time and has had many different genres but ''Empire Burlesque'' stands out being a uncharacteristic (though not for TheEighties) heavily produced synth pop affair (with one song even leaning slightly towards disco) and then he does it again in the same album by having it end jarringly with the quiet "Dark Eyes" a simply structured track that features only Dylan, a guitar and a harmonica without any studio embellishment whatsoever.
* {{JOJO}} did this in "The High Road" in this song Coming For You which is pop rock instead of loungy RAndB of the album.
* DaYoopers' 1992 album ''Yoopy Do Wah'', the last full album to feature original guitarist Joe Potila, was also the only album after their first not to include comedy skits between the songs. It also included "When One Love Dies", their first serious song since the EarlyInstallmentWeirdness of their debut.
* AlanJackson did this twice in 2006: first with a gospel album called ''Precious Memories'', then a few months later with ''Like Red on a Rose'', a smooth, ballad-heavy AC album that was a radical departure from his neotraditionalist country sound. The latter was also the only album of his career which Keith Stegall did not produce (bluegrass singer AlisonKrauss produced).
* The BeastieBoys' ''Aglio E Olio'' (a HardcorePunk EP) and ''The Mix-Up'' (an album of instrumental soul-jazz). Neither style was entirely new to the band[[note]] They actually started out as a hardcore punk band and occasionally made nods to those roots, and funk and jazz influenced instrumentals were prevalent on ''Check Your Head'' and ''Ill Communication''[[/note]], but they were still pretty unusual outings for a rap group.
* GeorgeStrait's 2009 album ''Twang'' is a double example: it had his first songwriting credits since his 1981 debut album, and it included a mariachi cover. 2011's ''Here for a Good Time'' includes more co-writer's credits, one being the ''very'' atypically dreary and downbeat "Drinkin' Man". The latter was his lowest peaking single to that point.
* Music/KennyChesney released ''Be as You Are (Songs from an Old Blue Chair)'' in 2005. It was a laid-back, acoustic album based around the song "Old Blue Chair" from his album ''When the Sun Goes Down'' two years prior. ''Be as You Are'' intentionally did not produce any singles. Despite being a side project, it went to #1 on both Top Country Albums and the Billboard 200, and was certified platinum. In a zig-zag of this trope, he also began including several laid-back, acoustic numbers on subquent albums as well.
* Japanese pop star Ayumi Hamasaki does this on most of her recent albums. 2005's "(miss)understood" started off with an upbeat gospel anthem only to jump to electropop 4 minutes later - and then to rock...and then dramatic over-the-top ballads. She somehow manages to put songs inspired by symphonic metal, classic rock, musical showstoppers, pop ballads and electropop in very, very close proximity on 2012's "Party Queen"
* Music/FlorenceAndTheMachine's "Kiss with a Fist" is more rock than all the other songs on the album ''Lungs'', due to being based off an earlier indie rock song called "Happy Fist".
* In the documentary ''Long Way to the Top: Stories of Australian Rock & Roll'', Angus Young of Music/{{ACDC}} recalls that, for some reason, the band decided to play the theme from ''ZorbaTheGreek'' at one show.
* EBM pioneers FrontLineAssembly pulled this at least twice, first with the IndustrialMetal album ''Millenium'', then the IDM/D&B album ''Flavour of the Weak'', and to a lesser extent the dubstep-influenced ''AirMech'' soundtrack.
* Kiss' 1981 album, "(Music From) The Elder", a concept album that featured an orchestra and choir. Universally regarded as the worst album of their career.
* Yes' 1984 comeback album, "90125", which focused more on shorter radio-friendly singles instead of the long, expansive, complex epics the band was known for in the 1970's.
* Music/MichelleBranch is a pop rock artist, but the final song on her debut album ''The Spirit Room'', "Drop in the Ocean", uses the BoleroEffect beautifully, starting from ambient, to slow-tempo pop rock, and then to drum & bass.
