Hard Rock Zombies.

Yes, there is a movie with that title. Yes, it involves EXACTLY what the title says.
The plot goes as follows:
A glam rock band goes to a small town to do a gig...only to be killed by a family of mutants, psychopaths, and ninja nazi midgets lead by Adolf Hitler (who was hiding in the U.S. through the use of Nazi magic). Fortunately the band recorded a song with words from a necromancy ceremony and are resurrected as undead rockers who kill the Nazis.
But then the nazis return as SUPER NAZI ZOMBIES and.....well, just watch the movie.
