My brother used to have a band, the bass guitarist's brother was a horror fanatic (it's always the drummers innit?) and, anyway, he had almost all of the Nasty List and a shitload of uncut goods on video... 2 per tape as I remember!
One of the most shocking double bills I ever saw was the uncut 'Dawn Of The Dead' and then 'Guinea Pig - Flower Of Felsh And Blood'... my jaw ****ing dropped I can tell you (this was around '94-95... did not have a clue!!).
However, the nipple slicing of The New York Ripper and the ferocious murders absolutely blew me away... there is a distinct sleazy and bitter taste to that film that cannot be ignored or forgotten... and you either love it or hate it.
4 DVD versions later and about 13 years down the line, guess which side I fall on?
