That's a perfect description of their sound xD
Oh yeah the first time I listened to Archspire was with the Relentless Mutation album. Specifically Involuntary Doppelgänger. And I started laughing because the vocals were so ridiculous xD but then my jaw dropped at the sheer speed they played at, and how FAST he could spit those vocals out.
Since then my appreciation for Archspire has only gotten stronger. Recently I watched them do song playthroughs and all I could say was 'holy sh!t' these boys are absolutely mental. especially the drummer
And Gene Hoglan is also a beast. He's been around the metal scene for a long time too. (He's even played in Testament. One of my all time favorite bands.)
