At one of the smaller clubs in Houston I caught prog-metal band Kamelot who were supported by Dragonforce.
I found Dragonforce to be basically be a one-trick pony (they all play super fast) and after a short time that trick got old.
Kamelot on the other gave a fabulous performance. The playing was tight and the members of the band seemed to be in fine spirits (2nd to last show of the current tour so maybe they were a little giddy).
My only complaint was the sound (very drum heavy) but that might be more the acoustics of the venue rather than any kind of control by the sound board.
