Kicking off its 16th year, the Van's Warped Tour held a preview at the Key Club in West Hollywood Friday night. Performing were a number of bands skedded for the summer jaunt, including party-rocker Andrew W.K. and Gossip Girl Taylor Momsen with her band the Pretty Reckless. Momsen channeled her best inner Courtney Love, displaying a surprisingly strongvocal prowess and ease on stage. The banddebuted tracks from their upcoming album, along with the ever popular "MakeMe Wanna Die" off the Kick Ass soundtrack. A little later, Andrew W.K. made a convincing argument that there's no substitute for high energy as he kicked off "It's Time to Party." Yet what has made Warped so popular isn't necessarily the big names, but rather the tour's up and comers.
