that's not far from the truth. when i saw them the dude ummm... i forget his name, some black metal dude did some screams for them, the drummer from Boris did a crucified-like stage dive, some more screams, and copious gonging. at the center was an effervescent fog machine, lots of tube amps, and approx. 3 chords.
it was like watching something out of Suspiria really. pretty nifty.
