For as long as metal has been around, people have associated the sound with "The Devil" and "Satanism." Locally, it's slim pickins' finding an actual Satanic metal band to chat with. I'm not talking "dressed in black" here; I'm talking blood-guzzling, church-burning, javelina-murdering dudes donning corpse paint with greasy long black hair.
I know they are out there, though, most notably in the depths of Norway, Sweden, England, and parts of Eastern Europe. Varg and Burzum, Venom and Celtic Frost: The influence of these bands is enduring. While I haven't been able to get any of those guys on the phone, I did recently chat with Cradle of Filth frontman Dani Filth. If you Google "Satanic bands," you'll find Cradle of Filth on many lists.
