Was there last night as well. I thought every band had great energy, but the sound wasn't that good a lot of times. I like Threat Signal a lot, but they were only ok in terms of performance. Especially Jon, his cleans are just really dissapointing live. I've only seen them once before, and it was in 2006 opening for Soilwork, but he was much better then. Again, maybe it was the sound. Even Bodom sounded muddy as hell during the first quarter or so of their set.
I still had a lot of fun, even though the Sound Academy is god awful in terms of everything. Had to take a shit in between Revocation and Eluveitie, which means the good spot you had is gone 5 seconds later. I'd honestly rather watch a show at the ACC or something.
