Ok, I'm a n00b for creating a new thread. Anyway...
I see there are some metal heads here. You guys owe it to yourself to listen to the "Deliverance" album by Opeth. It isn't as thrashy as Killswitch but it is definitely brutal as hell. The great thing about Opeth is the diversity. They released Deliverance and Damnation at the same time. One is pure evil metal and the other is prog ballad stuff. They are like the Pink Floyd of metal. Also check out Between the Buried and Me (BTBAM). They are a little to progressive for most but give em a listen.
