X-Offenders were a new wave-ska band popular on the local scene in the 1980s. They played area venues such as the Headquarters, Dance City, Journey, the Adams Avenue Theater, and the UCSD gym. Their songs earned airplay with tracks like "Layaway Plan" on local station 91X, and they opened for touring headliners such as Simple Minds, Untouchables, and The Call. The band released an EP in 1982 called Keeping Secrets.
The members included sax player Joe Asaro (Manual Scan, the Answers), guitarist Frank Glaser (later a cover artist for the Reader), drummer Billy Bischell, bassist Paul Fehlman, keyboardist Felipe Kolbo, and singer Mark Stuart. The youngest member, drummer Billy Bischel, passed away in November 2021.
