Nearly every song is about serial killers. Notable ones include:
"David Brom Took An Axe"
"Jeffrey Dahmer and the Chocolate Factory"
"Dr. Holmes - He Stripped Their Bones"
Many great albums including Gloom, Sinister Slaughter, Behind the Walls of Sleep, Unabomber, Dahmer, Morbid Campfire Songs, and Murder Metal.
While I dismembered the man attempting to break into my home, I was listening to "Serial Killer" by Macabre. My favorite band.
