The Jonas Brothers will perform at the Marcus Amphitheater on September 7th. It's just after Labor Day, and it's a school night. I don't know if that will hinder the ticket sales, but one would think that their drop in popularity, coupled with the show date will make this night an "off."
The Jonas Brothers have been white hot, and are now heading into the "burned out" realm. No offense to Jonas Brothers fans, or parents who love that their kids love them, it's just that everyone grows up.
