Emerson, Lake & Palmer were an English progressive rock supergroup formed in London in 1970. The band consisted of keyboardist Keith Emerson, singer, bassist, and producer Greg Lake, and drummer and percussionist Carl Palmer. With 4.5 million RIAA-certified albums sold in the US, and an estimated 48 million sold worldwide, they were one of the most popular and commercially successful progressive rock bands in the 1970s, with a musical sound including adaptations of classical music with jazz and symphonic rock elements, dominated by Emerson's flamboyant use of the Hammond organ, Moog synthesizer, and piano (although Lake wrote several acoustic songs for the group).

After forming in early 1970, the band came to prominence following their performance at the Isle of Wight Festival in August 1970. In their first year, the group signed with Atlantic Records and released Emerson, Lake & Palmer (1970) and Tarkus (1971), both of which reached the United Kingdom top five. The band's success continued with Pictures at an Exhibition (1971), Trilogy (1972), and Brain Salad Surgery (1973). After a three-year break, Emerson, Lake & Palmer released Works Volume 1 (1977) and Works Volume 2 (1977) which began their decline in popularity. After Love Beach (1978), the group disbanded in 1979.

The band reformed partially in the 1980s with Emerson, Lake & Powell featuring Cozy Powell in place of Palmer. Robert Berry then replaced Lake, forming 3. In 1991, the original trio reformed and released two more albums, Black Moon (1992) and In the Hot Seat (1994), and toured at various times between 1992 and 1998. Their final performance took place in 2010 at the High Voltage Festival in London to commemorate the band's fortieth anniversary. Both Emerson and Lake died in 2016, leaving Palmer as the only surviving member of the band.
