King Crimson

King Crimson are an English rock band formed in London in 1968. The band have undergone numerous formations throughout its history of which 21 musicians have been members; since 2013 it has consisted of Robert Fripp, Jakko Jakszyk, Tony Levin, Mel Collins, Pat Mastelotto, Gavin Harrison and Bill Rieflin. Fripp is the only consistent member of the group, and is considered their leader and motive force. The band has earned a large cult following.

Developed from the unsuccessful trio Giles, Giles and Fripp, the band were seminal in the progressive rock genre in their first five years with their standard of instrumentation and complex song structures. Their debut album, In the Court of the Crimson King (1969), remains their most successful and influential with its elements of jazz, classical, and experimental music. Their success increased following an opening act performance for The Rolling Stones at Hyde Park, London, in 1969. Following the less successful In the Wake of Poseidon (1970), Lizard (1970), and Islands (1971), the group reached a new creative peak with Larks' Tongues in Aspic (1973), Starless and Bible Black (1974), and Red (1974). Fripp disbanded the group in 1974.
