Emerson, Lake & Palmer

Emerson, Lake & Palmer, also known as ELP, were an English progressive rock supergroup which was formed in 1970 in England, United Kingdom. They found success in the 1970s and have sold over forty million albums and headlined large stadium concerts. The band consisted of Keith Emerson (keyboards), Greg Lake (bass guitar, vocals, guitar) and Carl Palmer (drums, percussion). They are one of the most popular and commercially successful progressive rock bands.

The ELP sound is dominated by the Hammond organ and Moog synthesizer of the flamboyant Emerson. The band's compositions are heavily influenced by classical music in addition to jazz and – at least in their early years – hard rock. Many of their pieces are arrangements of, or contain quotations from, classical music, and they can be said to fit into the sub-genre of symphonic rock. However, Lake ensured that their albums contained a regular stream of simple, accessible acoustic ballads, many of which received heavy radio airplay. Lake, besides providing vocals, bass guitar, electric guitar and lyrics, also produced the band's first five albums.
