Scary is subjective. I don't find most metal bands scary. Corny, but not scary. Well, Phil Anselmo scares me. That voice. I found Air Supply to be scarier than the bands listed below. But that's for reasons other than their stage show and their wonderful hair. Many punk bands would qualify as scary since the chances of having your eyeballs punched out was a clear possibility if you attended a FEAR concert.
However, in the spirit of Halloween, I went with bands who embodied the chance to live out your darkest fantasies and who may or may not have done a dance or two with Beelzebub. Most of them like costumes, too. Often are good with make-up and spectacular with hair. —Rob O'Connor
