Yeah, you guys are likely right. I've been to quite a few gigs, but most of them were small, unknown bands with absolutely no rapport with their audiences. The one really good gig I went to was Tommy Emmnuel in a crammed basement club. I wasn't even that much into his music--I went coz a flatmate invited me--but the guy was so entertaining and such a great muso that I really got into it. Steve Vai was fairly entertaining as well, though I don't listen to his music all that often when I'm at home.
Maybe I need to see a few big, famous bands that I like. The most popular guy I've seen has been--and I blame the wife for this one--John Mayer. I really enjoyed about 15 minutes of the whole concert. For the rest of the time my mind wandered and I couldn't wait to get out.
