I saw these guys open up for Anthrax on the 'Stomp 442' tour and they were amazing. One of the most brutal pits ever for an opening band.
The purple guy told me after the show that Steve DiGiorgio gave him private lessons and that was what made him the legendary bassist that we see on the vid here.
Also, he said the Hamburgular was getting all the pussy during the tour and the ho's were leaving him high & dry...so since my girlfriend at the time was a real nympho I lent her out as a courtesy to such a great musician and all-around great guy. She told me the next day he only did anal while Ronald videotaped.
I still have the tape. It's jerk-worthy.
