After Mick Jones was fired from the Clash in 1983, he formed Big Audio Dynamite (B.A.D.) one year later to continue the more experimental funk elements of the Clash's Combat Rock. The group's original incarnation included Jones, video artist and Clash associate Don Letts (effects and vocals), Greg Roberts (drums), Dan Donovan (keyboards), and Leo "E-Zee Kill" Williams (bass). Adding samplers, dance tracks, and found sounds to Jones' concise pop songwriting, B.A.D. debuted on record with the single "The Bottom Line" in September 1985 and the album This Is Big Audio Dynamite later that year. "E=MC2" and "Medicine Show" became sizable hits in England, and reached the dance charts in America.
