Shitty concert etiquette can destroy what could otherwise be an out-of-this-world concert experience. I've attended hundreds of metal, rock, and punk shows and witnessed all manner of drunken douchebaggery. The more intense the show, the more idiocy you'll have to put up with.
I'm not a people person. I don't go to shows to get shitfaced. I don't go to shows to intentionally collide with people galloping in a sloppy circle while shadowboxing. There's nothing wrong with either of those things, and I have no problem putting up with people who engage in them — I just want to enjoy an awesome live show.
Gogol Bordello played the Ritz Ybor last Monday. They were just as amazing as their last Bay Area appearance at the State Theatre, and I had an awesome time. Early on, however, I feared my evening would be ruined by the most egregious concert etiquette faux pas. An error so heinous it transcends rock shows and infringes upon normal everyday life.
