heavy shit
nice stuff, its got some awesome headbanging riffs
pretty heavy shit, it could be alot more "brutal" though
try tuning that shit down to drop A (unless thats already how you play, doesnt sound like it to me though), and try some tremolo picking on the low E string, that tends to have a pretty brutal sound
if you want some influence for brutalness, check out the band Whitechapel, they're the definition of brutal deathcore
anyways, keep up the good shit dude
