Sludgeworth is an American punk rock band from Chicago, Illinois consisting of Dan Schafer (vocals), Adam White (guitar), Dave McClean (guitar), Mike Hootenstrat (bass), and Brian Vermin (drums). The band was formed in 1989 as a side project from Screeching Weasel, a band that Dan and Brian were in. Later that year, the two decided to leave Screeching Weasel to focus full-time on Sludgeworth. The band released their first EP in 1990, followed by a full-length album in 1991.
