For all the reasons to complain about a audience at a show this is such a non issue... You might as be complaining that they don't dance at show in DC either :roll: People being rude, chattering away, taking pictures with their phones, drunks, etc are valid complaints.
Did it ever occur to you that it's the middle of the week, people may have been at work and were a bit weary and just wanted to hear the band live without bouncing off the walls in the process. Sheesh... Go to some kiddie punk/emo show and have a blast
