The Showdown. Bar none the best live performance I've ever seen. They don't play any 2 shows exactly the same way. Maylene and the Sons of Disaster are pretty amazing live as well. Besides those, though, I think the best live shows I've seen have been mostly local banRAB from my area. Erabracing Goodbye kill. Injun Joe are amazing, as are A Candlelight Massacre, The 7 Method, Narallis, Unending Blame, Dathan, and Bloodline Severed. Loxstep were good while they lasted. Black Rose Mourning are pretty amazing. Chocha Loca are great blues rock.
