UK was a short-lived British progressive rock supergroup founded by singer/bassist John Wetton and drummer Bill Bruford (both King Crimson alumni) with keyboardist/electric violinist Eddie Jobson (late of Roxy Music and Frank Zappa's band) and guitarist Allan Holdsworth. It existed between 1977 and 1980. Their 1978 self-titled debut album is regarded by many as a classic in the genre.
