Music like Vesuvius

The Rocker is a 2008 American comedy film directed by Peter Cattaneo, starring Rainn Wilson, Christina Applegate, Teddy Geiger, Josh Gad, Emma Stone, and Jane Lynch. The film was written by Maya Forbes & Wallace Wolodarsky, from a story by Ryan Jaffe.

In the late 1980s, Robert "Fish" Fishman (Rainn Wilson) is the drummer in Vesuvius, a fictional heavy metal/glam metal band from Cleveland, Ohio on the verge of making it big. The band is offered a recording contract with one condition - Fish must be replaced as drummer with the president of the record company's nephew. After initially refusing, the band caves when their manager tells them they would get to tour as the opening act for Whitesnake.
