System of a Down is an Armenian-American rock group consisting of lead singer/keyboardist Serj Tankian, backup vocalist/guitarist Daron Malakian, bassist Shavo Odadjian, & drummer John Dolmayan, formerly drummer/one-time vocalist Ontronik Khachaturian. The name ultimately derives from a poem written by Daron titled "Victims of the Down." They changed the name to "System of a Down" [[AscendedFanboy so that their CD's could be shelved closer to their musical idols]], {{Music/Slayer}}. In their early years, they were (more or less incorrectly) labeled NuMetal. This gradually subsided once the band gained further respect among both metal fans and the more critical segment of the mainstream. With that said, their sound isn't genre-definable but they sound similar to [[Music/HeavyMetal metal]], {{alternative|Rock}}, & {{progressive|Rock}}. In general, most of their work fits well enough under the general label of "rock" music.

In 2006 they parted ways to work on various non-System of a Down projects (Tankian's solo effort, ''ScarsOnBroadway'' formed by Malakian and Dolmayan, and Odajian's work with RZA); all of them except Malakian claimed this was an indefinite hiatus, but a lot of fans assumed it was more of a break-up, until they reunited for a tour in 2011. The band have continued to tour since, but it currently unclear if and when the band will record another album, although Dolmayan has said he would've liked to work on one in 2013, but so far, no material has been in production.

The band released five studio albums:
* ''[[SelfTitledAlbum System of a Down]]'' (1998)
* ''Toxicity'' (2001)
* ''Steal This Album!'' (2002)
* ''Mezmerize'' (2005)
* ''Hypnotize'' (2005)

Their lyrics often revolve around themes of isolation, insanity, and criticisms of modern society. Some of their songs have absurdist lyrics, others are sung as if speaking directly to the listener and feature terse statements and lots of questions/demands, and others yet are more sarcastic and satirical. [[SignatureStyle Probably their most well-known attribute is their rapid tone/tempo/time signature changes,]] giving the music a schizophrenic feel (most noticeable in songs like "Question!," "I-E-A-I-A-I-O," "BYOB," and, of course, [[SignatureSong "Chop Suey"]]).

They have been vocal in spreading word about the early-20th-century Armenian genocide (though Malakian has stated that "P.L.U.C.K." is their only song about said genocide[[note]]"Holy Mountains" from Hypnotize is too though.[[/note]]). They are also in favor of drug decriminalization & are strongly anti-interventionism.

!!Tropes found in their music:

* AerithAndBob: Serj, Daron, Shavo and...John.
* AlbumTitleDrop:
** ''Toxicity'' has one in the track it's named after.
** ''Hypnotize'' and ''Mesmerize'' each have a song that does this; see BookEnds below.
* AlternativeMetal: It's both an accurate and an [[NeoclassicalPunkZydecoRockabilly inadequate descriptor]] for them.
* AudienceParticipationSong:
** [[http://www.youtube.com/watch?v=K7yAO-QCSWA The video for "Boom"]] was shot by MichaelMoore during the ''massive'' worldwide anti-war protests in 2003. Most of the lines are sung by random protestors. It also includes a HarsherInHindsight moment when the video shows a the "scary" factoid that the war could cost $200 billion. The total cost is estimated to be [[http://costofwar.com/ in]] [[http://threetrilliondollarwar.org/ the]] ''trillions''.
** "Prison Song" becomes this live, as does the bridge for "War?"
** "Psycho." The audience sings the "PSYCHO! GROUPIE! COCAINE! CRAZY!" refrain.
* BawdySong: "Bounce", "Cigaro", "Violent Pornography", "I-E-A-I-A-I-O"
* BookEnds: ''Mesmerize'' and ''Hypnotize'' double-album, the one's outro echoing the other's intro ("Soldier's Side").
** ''Hypnotize'''s lyrics include [[TitleDrop 'They disguise it, hypnotize it' and 'Mesmerize the simple-minded'.]]
** The packaging for both albums interlock as well.
* CarefulWithThatAxe: Frequently, though mixed with other vocal styles as well. See SopranoAndGravel below.
* {{Crossdresser}}: "She's Like Heroin"
--> "He wants nothing less, [[SugarWiki/FunnyMoments but to wear a little dress]]."
* DigitalPiracyIsEvil: After outtakes from the ''Toxicity'' sessions were leaked to the internet as ''Toxicity II'', the band rerecorded most of the tracks, added some new ones, named it to ''Steal This Album!'' and changed the art to look like it was a burned CD with the title written with a Sharpie. More a parody or commentary than outrage, as they later said they don't care if fans download their music as long as it's after the work is released.
** They did some other things. They gave it no promotion and did not advertise it (ie, like a bootleg), and the album didn't even include a booklet in America. It does in the UK and Europe but it is a simple one sided sheet saying "Steal This Album!" on one side. Some copies of the US album had art [=CDs=] drawn by the band, something which is an occasional selling point of bootlegs.
** Interestingly, the band regard "Steal This Album!" as their third album indicating that they were satisfied with how it was released.
* DissonantSerenity:
** The stylistic disconnect between a frantic verse & a calm chorus ("Chop Suey", "B.Y.O.B.", "Viscinity of Obscenity", "Violent Pornography", among others).
** The song "Temper" from their second demo is the opposite of this, a relaxed, mid-tempo verse and a brutal grindcore chorus.
* DistinctDoubleAlbum: ''Mezmerize'' / ''Hypnotize''
* DownerEnding: "Lost In Hollywood"; "Soldier's Side" (reprise).
** On that note, all of their albums end depressingly. Their self titled debut closes with P.L.U.C.K., a song about young men forced to join the army in the wake of the Armenian genocide. ''Toxicity'' ends with "Aerials", a song about how selfish the human race is, and its hidden track is a tribal rendition of Armenian church hymn "Der Voghormya" (God Have Mercy). In addition, ''Steal This Album'' ends with "Streamline", a song about a man not being there for someone when they were on their death bed,
* EveryoneWentToSchoolTogether: Serj and Daron went to the same (Armenian-American, no less) grade school.
* EverythingIsAnInstrument: The end-section of "Aerials".
* ExcitedShowTitle: "Steal This Album!", "Chop Suey!", "Question!"
* FadingIntoTheNextSong: "Mind" into "Peephole."
** "Pictures" into "Highway Song".
** "Thetawaves" into "Roulette"
** Bonus points for the triple, "Holy Mountains" into "Vicinity of Obscenity" into "She's Like Heroin."
* GagPenis: "Cigaro."
-->''MY COCK CAN WALK RIGHT THROUGH THE DOOR!''
* GenreBusting: Not just as their musical style ({{Rock|AndRoll}}[=/=]{{hard rock}}[=/=][[AlternativeRock alt rock]]/[[AlternativeMetal alt metal]][=/=]{{progressive metal}}[=/=]{{progressive rock}}[=/=]Experimental[=/=]self-described as 'pop'), but the combination of clearly stated protest & absurdity.
** They even throw in some Armenian folk riffs into many of their songs, giving them a somewhat Middle Eastern flavor.
** The GenreBusting probably shouldn't come as any surprise since they've named FrankZappa as one of their primary influences. Indeed, several critics have compared them to Zappa.
* HeavyMetalUmlaut: "Nuguns" is written like this on the track listing.
* HiddenTrack: An adaptation of the Armenian hymn "Der Voghormia" (meaning "Lord Have Mercy"), after "Aerials".
* HumansAreBastards: Their lyrics tend to be very cynical and critical of society as a whole.
-->''Everybody, everybody, everybody living now. Everybody, everybody, everybody sucks!''
-->''[[ApeShallNeverKillApe Why must we kill our own kind?]]''
* IceCreamKoan: "Aerials", and arguably most of their repertoire.
* IndecipherableLyrics / SomethingSomethingLeonardBernstein: A lot of their music isn't quite indecipherable, but is quite hard to decipher.
** The fast vocal riff for "B.Y.O.B."
** Large portions of a lot of their more absurdist songs, such as "Vicinity of Obscenity", "Bounce", etc.
** From "Fuck the System":
---> I but a little bit bit bit show, but a little bit bit bit shame, but a little bit bit bit-BIT BIT BIT
** "I-E-A-I-A-I-O" flirts with this trope. The lyrics are decipherable, but performed at such high speed that it takes several re-listenings to make them out properly.
** "Chop Suey!" certainly is quite strange to listen to before you figure out the high-speed shouting.
---> WAKE UP! Ragabragamagalaka MAKEUP! Haddaskadafadawraka SHAKE-UP!
* IntercourseWithYou: "She's Like Heroin", "Violent Pornography", "Bounce", "Cherry/Virginity", and "Vicinity of Obscenity".
* LargeHam: Started out as Serj ("Sugar", "Bounce", pretty much most of the first two albums), but Daron slowly began to take the spotlight ("Needles", much of ''Mezmerize''[=/=]''Hypnotize''), while Serj sits at the {{Cloudcuckoolander}} ("This Cocaine Makes Me Feel Like I'm On This Song", "Vicinity of Obscenity", "Revenga", "Radio/Video") / DeadpanSnarker ("Cigaro") / occasionally TheQuietOne ("Lost in Hollywood") position. With the release of Serj's two solo albums, he's gone back to the LargeHam he's meant to be ("Lie Lie Lie", "Beethoven's {{C|ountryMatters}}unt", pretty much everything else).
* LastNoteNightmare: "Aerials", for one.
* LoudnessWar: To some extent, a LOT of their work, especially just about everything on ''Toxicity''.
** They're all Rick Rubin productions and three of their albums were mastered by Vlado Meller. Clipping is basically guaranteed, unfortunately.
* LyricalDissonance: Many, including "Bounce" (a very heavy song about group sex) and "Shimmy" (a hard song including lyrics about indoctrination and subjugation, also about wanting to dance all night and not being late for school).
** "Kill Rock 'n Roll", a heavy, serious song about the time Daron hit a rabbit with his car.(Note the cryptic lines "eat all the grass that you want / accidents happen in the dark".)
* MetalScream: Both Serj and Daron are good at these.
* MinisculeRocking: Just as an example, ''Steal This Album!'' is sixteen tracks over 43 minutes — that's just over 2:30 on average, with "Bubbles" just under two minutes long and "36" only forty-five seconds long. A song that lasts for four minutes or more is extremely hard to come by in general, though there usually is one track per album that exceeds five minutes and at least one other that equals or exceeds four (the sole exception being ''Steal This Album!'', where only one song exceeds four minutes in length and none exceed five).
** Both ''Mezmerize'' and ''Hypnotize'', despite being released separately, are under 40 minutes and so could have fit on a single CD.
* MohsScaleOfRockAndMetalHardness: Usually about a 7 or 8. Some of their ballads go as low as a 4 or so.
* MoodWhiplash: [[WordOfGod Serj himself]] has said "Bounce" coming right after "Chop Suey!" in the track listing is an example of this. Also, "Vicinity of Obscenity" being the next song after "Holy Mountains", and probably more.
* MotorMouth: One of the band's very defining characteristics. Almost every song by them has Serj singing really, ''really'' fast, [[UpToEleven so fast]] [[IndecipherableLyrics most of the lyrics can't be easily figured out with no help]].
* NWordPrivileges:
** Their [[InTheStyleOf reworking]] of "[[Music/WuTangClan Shame on a Nigga]]".
** "Will They Die 4 U?", their collaboration with Mase, Puff Daddy and Lil Kim from the ''WesternAnimation/SouthPark'' ''Chef Aid'' album, where Serj can be heard singing/shouting beginning on the second round of the chorus, while Mase raps it.
* NeoclassicalPunkZydecoRockabilly
* NewMediaAreEvil: {{Subverted|Trope}} by ''Steal This Album!'', as it essentially encourages the fans not to buy it, and nothing about the album suggests that SOAD was angry about the material being leaked or potentially "stolen".
** SOAD wasn't angry about the material being leaked at all, just that the songs weren't quite finished. They were happy to put out the material and present it like it was a bootleg. The band have absolutely no problem with people downloading their demo tapes, and have been known to play the exclusive material from them live.
** On the other hand "Violent Pornography" says [[OldMediaAreEvil "Turn off your TV!".]]
* NonAppearingTitle: "Stealing Society", "This Cocaine Makes Me Feel Like I'm On This Song", "B.Y.O.B.", "Chop Suey", "Chic 'n' Stu", "36", "U-Fig".
* OneHitWonder: Technically. "B.Y.O.B." is their only song to ever trouble the Top 40 of the Billboard Hot 100, achieving this feat with absolutely no help from pop radio and mostly from single sales, downloads and what little rock radio airplay contributes to Billboard Hot 100 chart placement. Subverted, however, in that several of their albums have sold more than ten million copies anyway.
* PrecisionFStrike: In the middle of "Lost in Hollywood", a slow ballad, Daron sings "All you [[ThisIsForEmphasisBitch bitches]] put your hands in the air and wave em' like you just don't care".
* ProtestSong: "B.Y.O.B.", "Prison Song", "Deer Dance", "Tentative", etc.
* PunctuatedForEmphasis: Repeated a few times in "Soil".
* RapMetal: Delved into this when they did a version of "[[Music/{{WuTangClan}} Shame on a Nigga]]"
* RidingTheBomb: Music video for "Boom".
* RockstarSong: "Radio/Video". Inverted by "Lost In Hollywood."
* SanitySlippageSong: The last 60 seconds of [[http://www.youtube.com/watch?v=5vBGOrI6yBk "Sugar"]] is a good example of this.
* ScienceIsWrong: "Science has failed our mother Earth."
* SelfTitledAlbum: Their debut.
* ShownTheirWork: "Prison Song" uses accurate (for the time) statistics in the lyrics.
* TheSomethingSong: "Prison Song" and "Highway Song".
* SopranoAndGravel: Serj does this all by himself on the first album, going from screeching to clean singing to guttural roars. Some of the clean singing on later albums is done by Daron.
* SubduedSection: Many, many songs. A few of the best examples are "She's Like Heroin", "Aerials", and "Chop Suey!".
* TitleTrack: ''Toxicity'' and ''Hypnotize'' both contain a straight example.
* UncommonTime: "Question!", a song with so many time signatures the band has had trouble performing it live. Many other songs as well, using time signatures like [[UncommonTime 6/8, 7/8, 6/4, 3/4 and 15/8]] (7/8 + 8/8 in the riff of the song "Soil") along with 4/4.
* UnusualEuphemism: The entirety of "Bounce".
** In a live version included on a bonus disc of some versions of ''Toxicity'', Serj drops the pretense that it's about pogo altogether and sings "I brought my pogo ''dick''".
* VocalTagTeam: Daron and Serj on later albums as Daron started singing more.
* WordSaladLyrics: Too many to list, but especially "I-E-A-I-A-I-O", "Vicinity of Obscenity", "Old School Hollywood", and "Question!"
** [[WordOfGod Daron admitted]] that "Suite Pee" was just a bunch of random lines strung together. Ditto "Sugar" and "Darts".
* XtremeKoolLetterz: "[[HeavyMetalUmlaut Nüguns]]," thanks to the umlaut.
