Zander Schloss (born August 7, 1958) is an American musician, actor and composer. He is perhaps best known as bass player for The Circle Jerks and The Weirdos and for his contributions to a number of independent (cult status) feature films. His first screen appearance was as "Kevin the Nerd" in Repo Man. He went on to appear in a number of Alex Cox films as well as significant musical contributions in other Cox features such as Sid and Nancy (1986), Straight to Hell (1987), Walker (1987), El Patrullero (1991) and The Winner (1996).
Born in St. Louis, Missouri, Schloss joined the Circle Jerks in 1984 after a two year stint with funk band The Juicy Bananas who contributed to the Repo Man sound track. He left the Jerks after two albums to join up with former Clash front man Joe Strummer in London as musical director and lead guitarist/multi-instrumentalist on several tours (with Latino Rockabilly War), solo albums and sound tracks. Schloss re-joined the Circle Jerks for their 1990 U.S. tour and continued to tour and record with the Jerks until 2010.
