Trick Or Treat
Lost Boys (not really "rock", but it's got the right image)
Spinal Tap
Slumber Party Massacre 2 (horrid, horrid plot, but I laughed through the entire thing...a greased, leather-clad rock star murderer singing and doing choreographed dance moves while killing scantily-clad women with a drill-guitar...ahahahahaha what cheesily amusing crap!)
