Heh, too many too count...Most, you wouldn't care about...Chilled with In flames, chilled with Children of Bodom, met Cannibal Corpse, met Dying Fetus....
Probably the most epic concert I've seen was actually the opening band! It was the band WAR opening for Steve Miller band. Steve Miller looked like one of my english teachers back in high school down to the sweater vest... IMO WAR was much better than the steve miller band way more energetic and funny. WAR did this sweet 20min version of Low Rider where every member of the band took a solo, this might sound horrible but they were so funny. They would start out in a normal solo then slowly morph it into something that would sound familiar. Then the whole band would play part of the song the solo morphed into, such as Iron Man Watching the band WAR rock out playing Iron Man had to be my best concert moment ever! Another cool concert (but not epic for me) was Velvet Revolver, especially because I got to go for free. We were right in front of a speaker tower, so it was like over powering mono sound... I wasn't stoked on losing hearing and not being able to hear what the hell was going on just noise basically. Ever since that concert I usually try to go near the back (that was 4th row) so I can actually hear the band and maybe save my ears a little.
