When RZ decided to concentrate on writing and movies in 2003, John Tempesta, who was Rob's drummer since White Zombie, and Mike Riggs, who did guitar work for Hellbilly and Sinister, decided to form Scum. Hince the similar sound to WZ and RZ.
Scum of the Earth is a song by Rob Zombie, a good one too. Can't help it if a guy like RZ makes others want to do what he does, he's damn good at it! This is a pretty good song by itself.
