Last night the Maynard James Keenan-fronted Puscifer made their television debut on Letterman performing the title track from their current release 'Conditions of My Parole.'

Puscifer joined 'The Late Show with David Letterman' last night, and despite the fact that it was Halloween -- the group was not in costumes. They actually dressed quite formally for the occasion. Even though Maynard looks like Ron Burgundy's long lost brother, you cant really call it a costume since that's his regular modus operandi.
