Before black metal, thrash, death metal, and grind had become strictly defined subgenres with their own cadre of stylistic schools, they all sort of overlapped in the middle; many bands kind of slopped over into most or all of them. Anal Vomit, though they've only been around a paltry 16 years, have been for the duration of their existence cranking out (mostly demos of) this omnivorously extreme throwback metal. Think the frantic hyperthrash of Morbid Visions-era Sepultura and Sarcofago (shocker: Anal Vomit is from Peru) bookended by Slayer on one side and Morbid Angel on the other. It has eminently been done before but for some reason Depravation is a fun listen anyway. This stuff is truly mired in the early days of what has become death and black metal. The guitars are a wall of constant doublepicking, cranking out sped-up Slayer riff after sped-up Slayer riff broken up occasionally by a squeal-y, dive-y, gibberish filled noise solo. The drums jackhammer away without fail, occasionally redlining into a slow blastbeat but mostly sticking to the very extremity of the standard thrash beat with the occasional kit-spanning tom roll tossed in for good measure. Bassist/vocalist 'Possessor' might as well just trash his inaudible instrument and stick to his ambiguously old-school rasp. Record it all on a four-track and dunk the whole mess in a tub of reverb and there you have it. Song-by-song analysis would be totally ridiculous here, as Depravation blows through in ten two-to-four minute chunks of frantic homogeneity.
