British band known for its role in the development of art rock during the 1970s. The members were Keith Emerson (b. Nov. 1, 1944, Todmorden, Lancashire, Eng.), Greg Lake (b. Nov. 10, 1948, Bournemouth, Dorset), and Carl Palmer (b. March 20, 1951, Birmingham).

Before the group made its debut in 1970, its members were veterans of the British art rock scene: keyboardist Emerson had formerly led the Nice, and Lake had been bassist and lead singer for King Crimson. ELP made synthesizer keyboards rather than guitars the centrepiece of its sound and developed an eclectic and innovative style blending classical music (music, Western), jazz, blues, electronic music (then still a novelty), and Tin Pan Alley. Their numerous albums (including six live albums, drawn from concerts featuring spectacular lighting and special effects) featured lengthy, elaborate original compositions such as “Tarkus” and “Karn Evil Number 9”; imaginative covers of serious classical compositions, most notably Modest Mussorgsky (Mussorgsky, Modest)'s “Pictures at an Exhibition,” Aaron Copland (Copland, Aaron)'s “Fanfare for the Common Man,” and the hilarious blues version of “Nutcracker Suite”; and occasional ballads or hymns, all played with great technical virtuosity.

ELP disbanded in 1979 but reunited in the early 1990s. However, as was the case with many re-formed 1970s rock groups, the trio's new recordings neither recaptured the passion of their earlier work nor struck out in new musical directions.
