The Bamboozle: Lil Wayne + Mötley Crüe + Bruno Mars + Taking Back Sunday + Wiz Khalifa + Dashboard Confessional + Waka Flocka Flame + 30 Seconds to Mars + Travie McCoy and more

The annual hip-hop/emo-pop extravaganza rolls back into town with a lineup to make an excitable, boozed-up teenager puke. Okay, so that's gonna happen anyway, but still. Lil Wayne heads up the hip-hop axis, which also features Amber Rose's current squeeze, Wiz Khalifa, and the excellent Waka Flocka Flame; while emo kids in hoodies can pump fists along to Dashboard Confessional and 30 Seconds to Mars. Also promised: the B-Boy Battle and the "BoozleTwist" interactive media program (it's okay, the kids understand it).
