This was a free club show headlined by DickTit and Runt. Runt was a band led by Steve Moramarco ("Steve Threw Up"/Bean). Those are the two bands on the flyer for the show.
The lead singer of DickTit recalled that not only was there a band with a young Jack Black there, but also that Beck asked if he could play a few songs between sets and they let him. (He also claims that Beck signed to Bongload on this night, but hard to verify that memory exactly.)
