I'm so stunned - you guys are talking about highly technical death metal and nobody has mentioned Decapitated. These guys are seriously a scary bunch of technical players - they're all trained at some music school in Europe. Nobody has mentioned Cynic either!! Or Death!??? Have we forgotten Chuck's groundbreaking work in the metal scene?! *flailing arms wildly*
Anyways, my vote is metal...
Strapping Young Lad, Slayer, Decapitated, Criminey, Cynic, Goatwhore, Damageplan, Death, Meshuggah, Dillinger Escape Plan, Soilwork, In Flames.....
