GG Allin meets Black Metal?

While browsing in the cheap dvd bin at some mom and pop record store, I came across a dvd from the band Kettle Cadaver.  The singer on the cover of the dvd was covered in blood and wearing the whole black metal leather and spikes uniform, so of course I was curious and picked it up.  When I first put on the dvd I was expecting a metal band, but really they sound more like a punk band.  They describe their music as "deathrock", which is cheesy as fuck.  Anyway, the point of this is that when I got a few minutes into the dvd, it went from music, to just watching a guy mutilate himself on stage.  He seriously made GG Allin look mild, and I've seen a lot of crazy shit on stage from sexual to painful, but nothing like this.  It actually made me cringe and I had to look away.  I am not gonna post any of that shit here, but here's an 'official' video of theirs to get an idea of the sound.

PS.  If you are so inclined to see hardcore shit, there is a clip of it posted on their myspace page linked above.
