The Mars Volta was a ProgressiveRock band from El Paso, Texas (curently based in Mexico) formed in 2001. ''Rolling Stone'' magazine named them the best prog-rock band of 2008.

Rodríguez-López and Parks went on to form a new project, Bosnian Rainbows. In addition, Rodríguez-López, Bixler-Zavala, and Hinojos' previous band, [[Music/AtTheDriveIn At the Drive-In]], has reunited; they released a new single in 2016 and have a new album projected for 2017. As of January 25, 2013, the Mars Volta has officially split up. As of April 2014, Rodriguez-López and Bixler-Zavala have [[ formed a new project entitled Antemasque]] (also featuring former Mars Volta drummer Dave Elitch and Music/RedHotChiliPeppers bassist Flea). This hasn't resulted in a reunion of the Mars Volta yet, but Rodriguez-Lopez has [[ indicated]] that he intends for one to happen; it seems to be mainly a matter of scheduling as to when (he wishes for founding members Eva Gardner and Jon Theodore to be involved).

!! This band provides examples of:
* AlbumIntroTrack: ''De-Loused in the Comatorium'' has "Son et lumiere."
* AltumVidetur: The song movement "Facilis descenus averni" translates as "Easy Is the Descent into Hell"; "Vade mecum" means "Go with Me"; "In absentia" is a legal term taken from Latin meaning "in absence" or "while absent".
* AnimalMotifs: There's lots of bird imagery on ''Frances the Mute'', with ravens, swans, and owls being prominently mentioned. Worms and snakes are also mentioned, in an apparently phallic context.
* ArcNumber: The number 25 is used a lot in ''Frances the Mute'', namely in the song "Cassandra Gemini". It's used in the lyrics, and around 10 minutes in you can hear it spoken ''very'' quietly.
* AwesomeMcCoolname: Try telling anyone the names Cedric Bixler-Zavala and Omar Alfredo Rodríguez-López are dull-sounding.
* BerserkButton: Cedric tends to get vocal about his dislikes, like moshing, and cigarettes.
-->'''Cedric (during the 09/13/2004 show):''' Hey, listen, man, if you guys came to see us, don't throw shit on the stage. Someone over there, one of you assholes, whoever threw it - I know youíre not all assholes - I mean, what the fuck were you thinking? When I go see my favorite band, Iím not gonna throw shit at them. You go do that at, like, Music/ThreeDoorsDown or fuckiní Music/LimpBizkit. I bet you guys are the ones who drive really bad too.
** Sadly later that day a girl was smothered during a moshpit and died not too long after.
*** At another live show someone threw beer at Cedric and between songs he said he would fight outside after the show and that he would "kick their fucking ass"
::: (Doubles as a TakeThat)
* BilingualBonus: Several songs have Spanish lyrics and one ("Asilos Magdalena") is entirely in Spanish. Amongst song/movement titles, "Tira me a las arañas" is slightly misspelled Spanish for "Throw Me to the Spiders"[[note]]it should be "Tírame a las arañas"[[/note]], "Cicatriz" translates as "Scar", "Con safo" translates as "With Soap", and "Asilos magdalena" translates as "Magdalene Asylums". Meanwhile, "una cavaletta" is a term for woman who constantly tries to change her lover into a fantasy she has conjured.
** Granted, Cedric's Spanish is mostly mispronounced on purpose to fit his vocal range.
* BookEnds: The "Sarcophagi" sections on ''Frances the Mute'' open and close the album; a whistling kettle in the first instance is also taken off the stove in the second.
* CallBack and CallForward: "Take the Veil Cerpin Taxt" features the phrase "It's not over 'til the tremulant sings", while "Eunuch Provocateur" contains the phrase "De-loused in the comatorium".
* CarefulWithThatAxe: Towards the end of "Goliath". There's also a random scream thrown in at about 3:20 into "Cavalettas".
* ConceptAlbum: Four of them, in fact:
** ''De-Loused in the Comatorium'': A man named Cerpin Taxt attempts suicide via a mix of morphine and rat poison, but instead falls into a coma for a week and experiences ''very'' strange hallucinations during this time. [[spoiler:He ultimately jumps off a bridge onto a freeway during rush hour.]] Very loosely based on the life and death of the band's friend, Julio Vanegas.
** ''Frances the Mute'': Based on a diary found by the band's late audio manipulator, Jeremy Ward, in the backseat of a car in his days as a repo man. The journal described a man's search for his biological parents. The names of those who led him to his parents were altered to create the titles of the songs. In the album's story, Vismund Cygnus goes searching for his mother Frances. [[spoiler:Turns out Cygnus and the people he spoke to were split personalities of Frances' that came about after she was raped by priests, hence every character's aversion to the church and why Frances went mute; she (or her personality Cassandra) ends up killing the priests at the end of the narrative.]]
** ''The Bedlam in Goliath'': The lyrics are based on sayings and events that the band encountered while using an old ouija board they found in Jerusalem, and the string of unpleasant events that they thought were due to a curse from the board. Bixler-Zavala later said it was a commentary on how women are treated in Islamic countries.
** ''Noctourniquet'' is said to be a concept album, somehow relating to Solomon Grundy from DCU, and Hyacinthus from Greek myth.
** As for the other two albums, ''Amputechture'' didn't have a specific story but was all about organized religion [[ReligionIsWrong and the things the band didn't like about it]]; while ''Octahedron'' had one or two songs being about reacting to the Republicans winning the election at the time ("Teflon"), or the Salem witch trials ("With Twilight as My Guide").
* CoverVersion: Six cover versions of songs by some of their favorite bands were recorded for use as bonus tracks on various versions of ''The Bedlam in Goliath''.
** Also their live cover of [[ "Broken English"]] by Marianne Faithfull, which takes an uptempo but dreary synthpop number and turns it into a [[ Santana-esque groove]].
* DeadpanSnarker: Cedric.
* DoesThisRemindYouOfAnything: According to an interview Cedric gave while promoting ''Octahedron'', the story of ''The Bedlam in Goliath'' is intended to be a metaphor for the way women are treated in Islamic countries.
* DrivenToSuicide: [[spoiler:Cerpin Taxt.]] This is pretty much a foregone conclusion since he's based on a real life friend of the band, [[spoiler:Julio Venegas, who committed suicide]].
* DroneOfDread: Used frequently on ''Frances the Mute'', notably in the intro to "Miranda That Ghost Just Isn't Holy Anymore" and the title track (which was released separately as a single).
* EpicRocking: They have some pretty lengthy songs, but topping them all is the 32-minute "Cassandra Gemini" from ''Frances the Mute''. Also notable because many of its musical themes were taken from live jams done in the middle of their previous longest song from ''De-Loused in the Comatorium'', "Cicatriz ESP", which would extend its length from 12 minutes (buffered by an ambient section in the middle) to 40+ minutes (all music). A live version of one of these performances is available on ''Scabdates'', although it also has eight minutes of MindScrew-inducing ambience inserted into the middle for some reason.
* FadingIntoTheNextSong: Every transition on ''Frances the Mute'' except the last one, which uses SiameseTwinSongs instead.
* GratuitousFrench: "Son et lumière" translates as "Sound and Light".
* HostageSituation: While ''Octahedron'' lacks a coherent story, the lyrics frequently allude to a deadly capturing scenario, in which the singer partook with some else. They are now estranged somehow.
* LargeHam: Cedric Bixler Zavala is one of the hammiest vocalists in progressive rock, a genre ''full'' of large hams. If a song has an epic chorus, it's probably because Cedric is chewing the scenery throughout it.
* LastNoteNightmare: The band ''love'' this trope. "Asilos Magdalena" might be the most obvious example, but "Televators," "The Widow," "L'Via L'Viaquez" and a number of other songs also qualify.
** Most notably, however, is probably [[ "Tourniquet Man"]]. Being the only quiet spot on the otherwise cacophonic ''The Bedlam in Goliath'', however, this was probably to be expected. Starting off slow but ominous, the vocals suddenly become horribly distorted halfway through, the backing synths slow down and slur, the drumming grows erratic, and the saxophone keeps on playing as if nothing had happened (though to be fair, Omar has a proud tradition of giving each musician their part and not letting them hear everyone else's part until the end of recording, so for all Adrian knew, nothing ''had'' happened).
* LeaveTheCameraRunning: this is used throughout ''Frances the Mute'' with the endings of songs, most likely for an ambient effect. The most prominent example may be "Miranda That Ghost Just Isn't Holy Anymore", which opens with four minutes of coqui frogs singing.
* LoudnessWar: Every single album has clipping, which in many cases is audible. ''Noctourniquet'' was so bad that even the mastering engineer [[!/hebakadryy/status/185105490387275777 criticised it]], claiming she was forced (by either the label or the band; it's not clear which) to master it that way. At least some of the vinyl editions also have clipping. Luckily there are [[ programs]] that can be used to [[ remedy this]]. Overall, the albums with the worst mastering are ''De-Loused'' (no surprise there as it was a Rick Rubin production) and ''Noctourniquet'', while ''Octahedron'' is less terrible about this than the others, but none of them are mastered well.
* MindScrew: Most of their lyrics and quite a bit of their music.
* MindScrewdriver: The [[ story]] the band wrote to explain the plot of ''De-Loused in the Comatorium''.
* MusicalPastiche: The segment between "They tied a rope around her legs and let her hang for seven days" and "This never happened" in the song "Frances the Mute" sounds like it belongs on one of the first two [[Music/JohnMcLaughlin Mahavishnu Orchestra]] albums (which are an acknowledged influence on the band). Other portions of the song sound like they were dropped in from a SpaghettiWestern soundtrack (and arguably qualify as an EnnioMorriconePastiche).
* TheNameIsBondJamesBond: "Cygnus....Vismund Cygnus"
* NeoclassicalPunkZydecoRockabilly: Their genre is hard to define, and has elements of Prog, Post-hardcore, Latin, and Electronic, amongst others. They are most frequently classified as ProgressiveRock, but even though this trope is frequently considered a necessary component of prog, it doesn't feel like an adequate descriptor.
* NothingIsScarier: Their ambient interludes like the ones on "Cicatriz ESP" and various segments of ''Frances the Mute'' (particularly the title track) can definitely have this effect.
* {{Portmanteau}}: At least three album titles bear one, let alone their song names.
* RapeAndRevenge: The story of ''Frances the Mute.''
* RealLifeWritesThePlot:
** Cerpin Taxt is based on a real-life friend of the band, Julio Venegas. [[spoiler:Because Venegas committed suicide, so does Taxt.]]
** The story of ''Frances the Mute'' is apparently inspired by a diary the band's late sound engineer, Jeremy Michael Ward, found while working as a repo man.
** The story of ''The Bedlam in Goliath'' is inspired by trouble the band experienced during the recording sessions of the album after they started using a ouija board.
** "Concertina" is another example, discussed under TakeThat.
** As mentioned above under ConceptAlbum, one of the songs on ''Octahedron'' was a response to the Republicans' victory in the 2010 Congressional elections.
** ''Octahedron'' has several songs that refer to kidnappings and ransoms, which Cedric has said occur commonly in Latin cultures. The band had two friends from Texas who disappeared without explanation, and they never knew "whether they simply took off or if they met with foul play".
* ReligionRantSong: Several songs on ''Amputechture'' are apparently examples, although it's sometimes difficult to tell with the WordSaladLyrics. There is a pretty anti-religious theme to the concept of ''Frances the Mute'' as well.
* RevolvingDoorBand: Cedric and Omar are the only constant members of a line-up that has changed countless times over the years. Most notably, the band has had three drummers since Jon Theodore left in 2006.
* SiameseTwinSongs: Most of the songs on ''De-Loused'' and ''Amputechture''. This didn't stop some of them from being released as singles.
* SplitPersonality: The most common interpretation of ''Frances the Mute'' is that [[spoiler:the named characters are split personalities of the title character that were created as a coping device after she was raped by priests. At the end of the album she, or her personality Cassandra, kills the priests.]]
--> ''I think I've become one of the others...''
* SubduedSection: Most of their long songs have one. "Cicatriz ESP" and "Frances the Mute" have especially creepy examples.
* SurprisinglyGentleSong: They have quite a few, such as "The Widow", "Televators", "Vedamalady", "Asilos magdalena", "Tourniquet Man", and probably over half of ''Octahedron''. Often they'll subvert this with a LastNoteNightmare, however.
* SurrealHorror: The band's music is frequently both surreal and terrifying. Their lyrics also often incorporate this.
* TakeThat: "Concertina" is rumoured to be a brutal attack on former Music/AtTheDriveIn member Ben Rodriguez, whom Omar and Cedric are on record as considering to be [[TheSociopath a sociopath]] and held as responsible for tormenting Julio Venegas to the point of his [[DrivenToSuicide suicide]].
* TextlessAlbumCover: Thus far, none of their full-length studio albums have had the band name or album title on the front, although the packaging will typically include a sticker with that information on it. Most of their singles or [=EPs=] do have a title and artist name on the front, as does the LiveAlbum ''Scab Dates''.
* UncommonTime: As they're a ProgressiveRock group, appearances of this trope in their work are pretty much mandatory. For example, on ''The Bedlam in Goliath'', "Metatron" (5/4), "Wax Simulacra" (11/8 or [6+ 5]/8), and "Cavalettas" (11/8 or [5+ 6]/8) are a few examples, but there are usually at least a few per album.
** "Cygnus... Vismund Cygnus" from ''Frances the Mute'' features a 6/8 intro, a 4/4 main section, a guitar solo and buildup in '''29/16''', followed by an explosive outro in 10/4.
** "Tetragrammaton" from ''Amputechture'' rotates through 11 different time signatures (including two areas with no time signature), and manages to count some uncommon times in multiple ways (one section in 12/8 is counted [5+ 5+ 2/]/8 every first measure and [4+ 4+ 4]/8 every second measure.) A full breakdown can be found [[ here]].
** "The Whip Hand" is a [[SubvertedTrope subversion]]. While it certainly seems like it has a very weird time signature, it's really just 4/4 syncopated very oddly.[[note]] Specifically, The first three bars have a 4:3 polyrhythm over them, with the last bar being a crochet. [[/note]]
* WidgetSeries: They're a weird Mexican-American thing.
* WordSaladHorror: Some of their lyrics veer in this direction. It's arguably the rule with them rather than the exception, honestly. Take "Miranda That Ghost Just Isn't Holy Anymore" for instance.
--> ''"And whoever said that they would scatter''\\
''Separating the mother from the child''\\
''She can bat a broken eyelid''\\
''Raining maggots from its sty''\\
''And with the traces that she leaves''\\
''She will skin you out alive"''
* WordSaladLyrics: It's very ''expressive'' word salad though. Their Spanish lyrics are usually quite a bit less word salad-y.
* WordSaladTitle: Their name.
** It's apparently supposed to be indicative of them being something "revolutionary", as per a quote by Creator/FedericoFellini where he defines his personal meaning of the world "volta" as a new turn of events. They just added in the "mars" because... well, [[RuleOfCool it sounds cool]].
