Brian Vermin (born Brian McQuaid) is a former punk rock drummer, best known for his time in Screeching Weasel and Sludgeworth. He joined Screeching Weasel in late 1988 at age 16, replacing original drummer Steve Cheese, when the band started its first serious touring. Brian appeared on the group's 1989 EP Punkhouse and a few compilations released in 1989 and 1990. In '89, Brian and SW bassist Dan Schafer formed a Sludgeworth as a side-project but the two soon quit Screeching Weasel in order to make Sludgeworth their focus. Brian participated in Screeching Weasel's 1990 reunion show but declined an invite to rejoin the band, citing the fact that he had more say in Sludgeworth's direction than he would in Screeching Weasel and also that he was not interested in the band's increasingly Ramones' influenced sound, noting that he "hated" the Ramones. Brian continued with Sludgeworth until their break up in 1993. He regrouped with the other Sludgeworth members to form Ethyline, with whom he played throughout the 1990s.
Today, Brian primarily creates custom home furnishings.
