Bandslam (2009)

A gifted singer/songwriter, Charlotte (Aly Michalka) hires Will Burton (Gaelan Connell), a new guy in town, to manage her fledgling rock band. She wants one thing from him: to help her win a contest against her ex-boyfriend in an upcoming battle of the bands. Charlotte's band comes together and seems to have a real shot at victory, while Will and dynamic guitarist Sa5m (Vanessa Hudgens) begin to make some beautiful music of their own.
