ELP – Emerson, Lake & Palmer.
Emerson, Lake & Palmer (ELP) were an English progressive rock supergroup. In the 1970s, the band was extremely popular, selling over 35 million albums and headlining huge concerts. The band consisted of Keith Emerson (keyboards), Greg Lake (guitar, bass guitar, vocals) and Carl Palmer (drums, percussion). In late 1973, Brain Salad Surgery, with an eye-catching sleeve designed by H. R. Giger, was released and became the band’s best-known studio album.
