Hard Rock Zombies (1985)

A hard rock band travels to the tiny and remote town of Grand Guignol to perform. Peopled by hicks, rubes, werewolves, murderous dwarves, sex perverts, and Hitler, the town is a strange place but that doesn't stop the band's lead singer from falling in love with a local girl named Cassie. After Nazi sex perverts kill the band to satisfy their lusts, Cassie calls the rockers back from the grave to save her, the town, and maybe the world.
