In 1989, Schafer became the bass player for
Screeching Weasel, though he switched back and forth from bass to guitar several times over the band's history. He performs under the pseudonym Dan Vapid or Danny Vapid, although he was originally called Sewercap when he joined the band. Screeching Weasel disbanded when Schafer and Brian Vermin, the drummer, quit the band to concentrate on their side project,
Sludgeworth. Schafer spoke about his time with Screeching Weasel in a March 2011 interview with Jason Duarte for Squid Pro Quo. Screeching Weasel has been through many incarnations, some which include Schafer and some which do not. He was the guitarist for the 2011 version of the band, which did not include founding member
John Jughead. That version of the band ended on March 23, 2011 when all the members quit the band following an incident at
SXSW. ==Sludgeworth==
