Sludgeworth was a punk band from Chicago, consisting of Dan Vapid (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. They released their first EP in 1990, followed by a full-length album in 1991. That same year, Vapid joined a resurrected Screeching Weasel. Sludgeworth announced their split in late 1992. The breakup was due to musical differences between Schafer and the other members, with the former wanting to continue playing pop punk and the others wanting to move in a different direction. Sludgeworth played their last show in early 1993. A few years later, a collection of their music was released by Lookout! Records on the album Losers of the Year.
