Emerging in the mid-2000s, Boston, Massachusetts extreme metal trio Revocation are armed with a super-technical thrash/death metal style that prizes virtuosity as much as heaviness and aggression. Originally operating under the moniker Cryptic Warning, the band found favor with the metal underground via a pair of well-received demos and a full-length. After changing over to Revocation in 2006, the group racked up accolades with virtuosic blasts of uncompromising thrash like Deathless (2014), The Outer Ones (2018), and Netherheaven (2022).
