Revocation is an American technical death metal/thrash metal band. Characterized by their [[NeoclassicalPunkZydecoRockabilly highly eclectic]] sound that combines elements of countless metal and non-metal genres, as well as frontman David Davidson's unique, versatile guitar style, Revocation has made a tremendous rise in a short period of time, having netted a lucrative contract with heavyweight metal label Relapse Records, as well as embarking on numerous high-profile tours, and it doesn't look as if they're going to stop any time soon.

Formed in Boston, Massachusetts in 2006 from the ashes of Cryptic Warning, the initial lineup consisted of David Davidson (guitars, vocals), Anthony Buda (bass, vocals), and Phil Dubois-Coyne (drums), the group released a three-song demo that same year and quickly made a name for themselves in the Boston area, being a local favorite at bars and basement booze-ups alike. They later went on to self-release ''Empire of the Obscene'', their first full-length, in 2008; it launched to very positive reviews that, along with the subsequent self-financed tour, were enough to attract the attention of Relapse, who promptly signed the band. Their drive further enhanced, they released their follow-up, ''Existence is Futile'', in 2009. Everything continued to go smoothly, and the band added Dan Gargiulo (guitars, vocals) in 2010 in order to expand their options both in the studio and live. This slightly altered lineup would then go on to release ''Chaos of Forms'' in 2011. Things kept moving forward until sometime in 2012, when Anthony quit the band to pursue a musical career of his own; replacing him was Brett Bamberger of East of the Wall fame. This new lineup quickly released ''Teratogenesis'', a free EP, in September 2012 through Scion A/V; as of the writing of this article, they just started a two-part US tour with A Life Once Lost and KEN mode for the first half, with the Faceless and The HAARP Machine taking over for the second leg. Not bad for a few boys from Boston (and Jersey, in Brett's case).

In August 2013, the band released their [[SelfTitledAlbum self-titled]] fourth album. After their contract with Relapse expired, they signed with Metal Blade Records in 2014 and released ''Deathless'', their fifth full-length, that same year. As of 2015, Phil Dubois-Coyne has announced his exit from the band, citing numerous life circumstances that led to his having to make that decision while also stressing that there is absolutely no bad blood and that they are still his best friends. As of June 26, 2015, [[Music/ThreeInchesOfBlood Ash Pearson]] is officially their new drummer, though he has unofficially held that slot since at least April.

----
This band contains examples of the following tropes:
* AgentPeacock: Phil, Phil, '''PHIL'''.
* AllDrummersAreAnimals: Phil had a powerful, energetic playing style that was coupled with his infamous offstage antics and bawdy sense of humor.
* AscendedExtra: Dan started out as a live guitarist out of necessity due to how some of their more complex newer material just didn't work live with one guitarist. He was gradually given a bigger role in the band, going from contributing backing vocals and a few leads on ''Chaos of Forms'' to becoming the second vocalist outright after Anthony Buda left and writing multiple songs per album.
** Similarly, Ash Pearson started out as a live fill-in for Phil on a European tour with Aeon and Cannibal Corpse; once Phil decided to leave for good, Ash was officially selected as their new drummer.
* AudienceParticipationSong: "Dismantle the Dictator".
* BadassBeard: Brett. Dave is also getting there.
* CareerEndingInjury: Subverted with Phil. Yes, some shithead cop did indeed get overzealous and badly fractured his arm while placing him under arrest, and while it did play a fairly major role in Phil's decision to step down, it was not the only reason by any means and also was not quite bad enough to prevent Phil from ever playing drums again or even just playing at his pre-injury level of skill.
* ChildPopstar: They were all in their mid-teens when they formed as Cryptic Warning. Doubles as a collective case of TeenGenius because of the level of technical skill that they possessed even then.
* CloudCuckooLander: Phil had a strange and frequently perverse sense of humor.
* CoverVersion: "Death in Vain" (Exhorder), "[[Music/{{Death}} Pull the Plug]]", "[[Music/FaithNoMore Surprise! You're Dead!]]", "[[Music/{{Metallica}} Dyers Eve]]", and "[[Music/MorbidAngel Sworn to the Black]]".
* DarkerAndEdgier: ''Teratogenesis'', which was noticeably more death metal-leaning than the previous albums. ''Deathless'' appears to go even further in this direction.
* EldritchAbomination: Some of the characteristics of the [[KrakenAndLeviathan titular monster]] in "Leviathan Awaits" certainly evoke this, while the creatures from "The Watchers" seem to be the [[Creator/HPLovecraft Fungi of Yuggoth]]. Finally, "A Visitation" appears to be about a reality incursion by beings akin to this.
* EpicRocking: "Exhumed Identity" (6:52), "Suffer These Wounds" (6:11), "Tragedy of Modern Ages" (7:03), "Madness Opus" (6:23), and "Witch Trials" (6:03).
* GenreRoulette: ''Existence'' had elements of this, but ''Chaos'' really brought this out. You have straightforward technical death ("Cretin", "Beloved Horrifier", "Reprogrammed"), progressive death ("Dissolution Ritual", "Conjuring the Cataclysm", the title track, "The Watchers"), a straightforward death/thrash track ("Harlot"), a heavily power metal-influenced song ("Cradle Robber"), a Megadeth-esque technical thrash song ("No Funeral"), something that could've been a lost Coroner track ("Dethroned"), and a technical instrumental in the vein of Spastic Ink ("Fractal Entity").
* HeavyMeta: "Deathless", primarily in regards to the touring life.
* IconicItem: With his rapidly rising status as a modern shred icon, Dave's 7-string Jackson Warrior with maple finish is fast becoming one of these.
* {{Instrumentals}}: "Alliance and Tyranny", "Stillness", "Enter the Hall", "Across Forests and Fjords", "Fractal Entity", "Spastic", and "Apex".
* InTheStyleOf: "Fractal Entity" and "Spastic" are technical instrumentals in the style of Spastic Ink (who were a huge influence on the band as a whole, especially on Dave, who worships Ron Jarzombek), which the latter's title hints at.
* LeadBassist: Anthony Buda was a Type B.
* MeaningfulName: They chose their name because they wanted a fresh start from the mistakes that they made as Cryptic Warning; in essence, it was a revocation of all of their earlier bad decisions.
* MelodicDeathMetal: Particularly from ''Teratogenesis'' onwards as they've steadily moved away from thrash.
* MetalBandMascot: Unofficially, there's Hoss the [[GagPenis giant dildo]], the likes of whom is primarily used for pranks on other musicians.
* MohsScaleOfRockAndMetalHardness: Hard 9 for the most part, soft 10 on the heavier songs. Their absolute heaviest tracks ("Empire of the Obscene", "Reprogrammed", "Teratogenesis", "Madness Opus") are easily a solid 10.
* NeoclassicalPunkZydecoRockabilly: As the years have gone on, they've thrown in tons and tons of genres and made them work. In addition to death and thrash, they've used jazz fusion, blues-rock, Southern rock, funk, surf, post-metal, 80s shred, 70s hard rock, progressive rock, bluegrass, and even some Tower of Power-esque horn sections.
* NewSoundAlbum:
** ''Existence'' increased the melody a bit and included a wider variety of genres.
** ''Chaos'' majorly amped up their GenreRoulette and NeoclassicalPunkZydecoRockabilly tendencies.
** ''Teratogenesis'' completely dropped the eclectic focus of previous albums and went for a more straightforward technical death sound, as well as being their first album to make use of seven-string guitars, the likes of which were used in a manner suggestive of a Music/{{Nevermore}} influence.
** The self-titled brought back a little bit of the eclecticism present on ''Chaos'' while still going with the heavier, darker feel of ''Teratogenesis''.
** ''Deathless'' further expanded upon the death metal leanings that ''Teratogenesis'' established while also taking an even more technical turn overall, in addition to dialing down the genre-hopping.
* NoExportForYou: Their cover of Exhorder's "Death in Vain", which was a Japanese bonus track on ''Existence'', as well as their cover of "[[Music/{{Metallica}} Dyers Eve]]" on the self-titled, but that is slightly subverted insofar as the Japanese version of the self-titled was also offered in the US in very limited quantities as a preorder.
* OldShame: Their Cryptic Warning days, to some degree; they're not too happy with them, but it's less about the music itself and more about the naivety and lack of foresight they displayed, culminating in the less-than-stellar production job of their full-length that was due to their picking the first producer that they found regardless of his actual experience with metal.
* PoliceBrutality: The reason why Phil didn't play any shows with the band for over eight months before finally leaving. While being arrested for drunk and disorderly conduct, the arresting officer apparently bent his arm in a way that caused multiple fractures and, for lack of a better term, completely fucked it up. While it wasn't the sole reason for his departure, it ''definitely'' didn't help.
* PromotedFanboy: Dan.
* RockTrio: Started out as this. They added Dan in 2010 because a lot of their newer material wound up not really working live without a second guitarist.
* SignatureStyle: Heavily riff-based music with riffing that runs the gamut from crushing, mosh-friendly death metal to laid-back, jazz fusion-tinged progginess, noticeable melodic overtones, technical, melodic soloing that owes as much to fusion as it does to Shrapnel Records-style shred, and vocals that usually stick to a mid-ranged shout along with occasional gutturals or shrieks. Also expect lots of genre hopping and major tempo changes.
* SopranoAndGravel: Dave does the mid-ranged harsh vocals, while the high shrieks were handled by Anthony when he was in the band and are currently handled by Dan (though his are somewhat lower and raspier). Additionally, Dave has been sporadically using cleans since ''Chaos of Forms''.
* SpecialGuest: [[Music/JobForACowboy Jon Rice]], [[Music/ThreeInchesOfBlood Ash Pearson]], and [[Music/TheFaceless Alex Rudinger]] have filled in for Phil on the past three respective tours, as he broke his arm and has been unable to make the shows; as of now, Ash has crossed over into AscendedExtra territory and is now a full-time member. Additionally, [[Music/{{Aborted}} Sven de Caluwe]] joined them onstage as a guest vocalist for "Madness Opus" during a European tour with Cannibal Corpse and Aeon.
* StartMyOwn: Subverted with Dan and Artificial Brain, as they were around before he joined Revocation. That being said, they never released anything prior to Dan joining the latter, so you could be forgiven for thinking that he started the former as a side project.
* TheStoner: Dan.
* TechnicalDeathMetal: Natch.
* ThrashMetal: Part of their overall sound, especially early on. This has been dialed down over the years as they've moved more and more towards death metal.
* UncommonTime: Very often.
* VocalEvolution: Dave started out with a higher, more shout-like style that occasionally invited comparisons to metalcore; as time went on, he gradually lowered it to more of a growl and also started using cleans on ''Chaos of Forms'' on an intermittent basis.
* WriteWhatYouKnow: "A Debt Owed to the Grave" was inspired by the time that Dave spent working in the morgue of a hospital, as his job largely entailed moving bodies down to the basement. At face value, it's about leaving payment for Charon, but it's also just as much about his realization that he essentially was a ferryman for the dead.
* XMeetsY: [[Music/{{Exodus Band}} Exodus]] meets Music/{{The Faceless}} meets Music/{{Death}} meets Music/{{The Dillinger Escape Plan}}. Yes, really.
