Poison the Well is so boring live. A hardcore band that stands around. Woot.
I really like seeing Between The Buried and Me play because I just stand there in amazement. Killswitch Engage is one of the best sounding bands I've seen live. The best performance, however, goes to a band from Syracuse, Ed Gein. Tech metal/grindcore at its best. They broke almost all of their equipment 2 of the 3 times I saw them.
