Keith Noel Emerson (born 2 November 1944 – 10 March 2016) was an English keyboardist and composer. He was formerly a member of the Keith Emerson Trio, John Brown's Bodies, The T-Bones, The V.I.P.'s, P.P. Arnold's backing band, The Nice, and Emerson, Lake & Palmer (ELP), one of the early supergroups. Emerson first found success with The Nice in the late 1960s before going on to become a founding member of ELP in 1970. ELP were critically and commercially successful through much of the 1970s, becoming one of the best-known progressive rock groups of the era. Following the break-up of ELP, circa 1979, Emerson had modest success with Emerson, Lake & Powell in the 1980s as well as with 3, with the album To the Power of Three. ELP reunited during the early 1990s, releasing the album Black Moon.
