I play black metal, and most black metal musicians put theirselves ultra ridiculous names like "necrobutcher". I also always though the corpse painting was a bit ridiculous, I never did (and prob never will) painting and I so far always use my real name, even if it's not "tr00 black metal" at all
For a brief time in the 80's, I was Jammin' Jay Suckmeblind.
It seemed like a good idea at the time...
