I am one of those, and always have been. I go to a concert to hear the music performed live, by my favorite musicians. Maybe it's my background in classical music, or maybe it's just that personally I'm boring as fuck, but I don't give a damn about the "show" or the "fun factor". I'll sit quietly and enjoy a great musical performance, whether it's classical, jazz, rock and roll, or anything else. I'll sit quietly and enjoy a great performance of music I don't even like. The people around me standing up and screaming... I wish they'd just sit down and shut the fuck up. I'm trying to hear the music.
