This is exactly what the relatively new newly formed grind core band called PURE, consisting of very well-known figures of our underground scene. Originally a jam project of members and ex-members of the bands like But, Ingrowing, Uprise, Pigsty or Force of Hell has moved on to active playing and recording.
PURE is releasing their first big record these days and the guys are finally starting to play live, and one of their first live shows supporting Suffocation themselves nearly blew our minds with the intensity!!! Expect real hell on earth from PURE!!! Grindcore par excellence!!!
