Comprised of veterans of the Portuguese metal underground, Perpetratör features current members of Filii Nigrantium Infernalium, Ravensire, as well as ex-members of The Firstborn and Omission. Their sound is a departure from their other bands, however, specializing in an absolutely blistering iteration of old-school Teutonic thrash metal. In their unrelenting 2014 debut album, “Thermonuclear Epiphany” expect nothing but pure fist-in-the-face diabolism and debauchery!
