Emerson, Lake & Palmer were an English progressive rock supergroup power trio who sold over forty million albums. The band consisted of Keith Emerson (keyboards), Greg Lake (bass guitar, vocals, guitar) and Carl Palmer (drums, percussion). They were one of the most popular and commercially successful progressive rock bands. ELP's sound was dominated by the Hammond organ, Moog synthesizer and piano of flamboyant virtuoso Emerson and heavily influenced by classical music as well as jazz and hard and symphonic rock. Lake ensured that each album contained at least one simple, accessible acoustic ballad, many of which received heavy radio airplay. (More from Wikipedia)
On June 6, 1966, Keith Emerson – later a founding member of the Nice and Emerson, Lake and Palmer – told Bruno Ceriotti that he was in the audience for a performance by the Soul Agents at the Marquee Club. As reported by Ceriotti on his blog: "The not yet famous organ God Keith Emerson was in the audience during one of the band's Marquee shows that summer, and was duly inspired by Don Shinn's act that featuring hilarious stage antics such as a habit of disappearing around the back of his organ to draw out weird sounds with the aid of a screwdriver, and also 'treated' adaptations of classical pieces such as an arrangement of Edvard Grieg's Piano Concerto in A Minor, one of the most popular of all piano concerti. Seeing Don Shinn do that, made Keith Emerson realise that he'd like to compile an act from what Don did."
