This is an absolutely bonkers and very low-budget movie that features several music numbers from a glam metal band called Holy Moses and sort of reads like an extended music video. The band has to play in a small conservative town, where the locals are openly hostile toward them, but they are given refuge by a weird wealthy family who, as it turns out, is the family of Adolf Hitler and Eva Braun. The lead singer, Jesse (some guy named E.J. Curse) falls in love with an underage girl named Cassie (Jennifer Coe), while also somehow developing a bass riff that raises the dead. The psycho family murders them all, prompting Cassie to play a recording of a song that uses the aforementioned bass riff, and that causes a zombie outbreak.

The trailer I included is pretty poor quality but I wasn't able to find a cleaner copy.
