Released in the UK as a mostly solo piece-oriented album in late 1970 and early 1971 in the U.S., Emerson, Lake and Palmer’s self-titled debut album included arguably their most famous song, “Lucky Man.” Three of the albums tracks were instrumentals, “Barbarian,” “The Three Fates,” and “Tank.” “Lucky Man” was released as a single, backed with “Knife Edge.” The album overall was well recieved by both Rolling Stone and Allmusic, but garnered a C rating from critic Robert Christgau. The musical content of the album both introduced and explored Emerson’s interest in classical compositions, and made heavy use of organs and synthesizers.
