EXCLUSIVE Clip: 'Bandslam' Turns Vanessa Hudgens Into A Guitar Hero

"High School Musical" starlet Vanessa Hudgens is rocking out another tune these days: Her upcoming movie "Bandslam." In the high school flick, the former Wildcat joins a fledgling rock group, which was formed by a geek (newcomer Gaelan Connell) and a popular girl (Aly Michalka) in the hopes of winning the school's battle of the bands. The movie isn't out until August 14, so if you can't wait until then, press play below for an exclusive first look. You won't want to miss checking out Vanessa's guitar skills (or the band's performance of "I Can’t Go On, I’ll Go On”), which she learned specifically for the film. Wonder if she's given Zac Efron any lessons...
