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, and have recently signed with Metal Blade and are already working on a followup, which will be called ''Deathless'' and released in fall 2014.

This band contains examples of the following tropes:
* AgentPeacock: Phil, Phil, '''PHIL'''.
* AllDrummersAreAnimals: Phil has a powerful, energetic playing style that is coupled with his infamous offstage antics and bawdy sense of humor.
* AudienceParticipationSong: "Dismantle the Dictator".
* CloudCuckooLander: Phil has a strange and frequently perverse sense of humor.
* CoverVersion: "Death in Vain" (Exhorder), "[[Music/{{Death}} Pull the Plug]]", "[[Music/FaithNoMore Surprise! You're Dead!]]", and "[[Music/{{Metallica}} Dyers Eve]]".
* DarkerAndEdgier: ''Teratogenesis''.
* 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", "Suffer These Wounds", and "Tragedy of Modern Ages".
* [[FiveManBand Four Man Band]]:
** TheLeader: Dave
** TheLancer: Phil
** TheBigGuy: Dan
** TheSmartGuy: Brett
* 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 math-influenced technical instrumental ("Fractal Entity").
* {{Instrumentals}}: "Alliance and Tyranny", "Stillness", "Enter the Hall", "Across Forests and Fjords", "Fractal Entity", and "Spastic".
* LeadBassist: Both of their bassists have qualified for Type B and C, being both frequent songwriters and backing vocalists. They're also quite skilled from a technical standpoint, but unlike most tech-death acts, there isn't a particularly large emphasis placed on the bass-work.
* MohsScaleOfRockAndMetalHardness: Hard 9 for the most part, 10 on the heavier songs.
* MelodicDeathMetal
* MetalBandMascot: Unofficially, there's Hoss the [[GagPenis giant dildo]], the likes of which is primarily used for pranks on other musicians.
* 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 fusion, blues-rock, Southern rock, funk, surf, post-metal, first-wave metalcore, 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''.
* 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.
* TechnicalDeathMetal: Natch.
* ThrashMetal: Despite being labelled as this, they aren't overly thrashy. It certainly does factor into their sound, however.
* UncommonTime: Very often.
* XMeetsY: [[Music/{{Exodus Band}} Exodus]] meets Music/{{The Faceless}} meets Music/{{Death}} meets Music/{{The Dillinger Escape Plan}}. Yes, really.
