Mr-Clam, I was really thinking about letting you in, but the comparison between the "technical aspects" of Trivium and Cannibal Corpse is retarded.
Bass playing: Alex Webster rules, he is a great, highly-skilled player, where Trivium's bass is simple and just follows the guitars.
Guitars: I don't doubt Heafy's ability to play, but ripping off others is not the right way. Btw, Pat O' Brien and Rob Barrett are also great players and their complex riffs and difficult time signatures, as well as highly technical solos are a force to be reckoned with. (Jack Owen is an amazing player as well, he only left CC a few years ago).
Corpsegrinder's vocals are way better than Heafy's gay singing and hardcore rapping.
Paul Mazurkiewicz's drumming is also quite technical. Listen to their "Kill" album and obey.
Sorry, you might be interested in metal, but your knowledge is VERY limited and your wise-ass-ness does not fit your ability to differ between -core and metal.
