Brain Salad Surgery

Brain Salad Surgery is the fourth studio album by progressive rock band Emerson, Lake & Palmer, released in 1973 and the first under their Manticore Records imprint. It fuses rock and classical themes. Greg Lake wrote the lyrics for the album with the assistance (on two tracks, "Karn Evil 9: 3rd Impression" and "Benny the Bouncer") of former King Crimson bandmate (and, beginning with this album, frequent ELP collaborator) Peter Sinfield. This was the first Emerson, Lake & Palmer album to have no songwriting contributions from Carl Palmer. The cover art is by H. R. Giger.

Music

After the release of Trilogy, the band wanted to record an album that they could perform live; Trilogy was recorded on the newer 24-track machines with overdubbing that made the music difficult to recreate on stage. The band purchased a cinema and would perform the music "live" on stage, then write, perform again, write, etc., resulting in a feeling of addressing the audience directly.

Jerusalem

"Jerusalem" is an adaptation of Hubert Parry's hymn, with lyrics from "And did those feet in ancient time", a poem from the preface to William Blake's "Milton a Poem". Debuting on this track is the Moog Apollo, the first polyphonic synthesizer, still a prototype at the time.
