Emerson, Lake & Palmer released the progressive rock album Tarkus.

Emerson, Lake & Palmer were an English progressive rock supergroup formed in London in 1970. The band consisted of Keith Emerson (keyboards) of The Nice, Greg Lake of King Crimson, and Carl Palmer of Atomic Rooster. With nine RIAA-certified gold record albums in the US, and an estimated 48 million records sold worldwide, they are one of the most popular and commercially successful progressive rock groups of the 1970s, with a musical sound including adaptations of classical music with jazz and symphonic rock elements, dominated by Emerson's flamboyant use of the Hammond organ, Moog synthesizer, and piano.

Progressive rock is a broad genre of rock music that primarily developed in the United Kingdom through the mid- to late 1960s, peaking in the early-to-mid-1970s. Initially termed "progressive pop", the style emerged from psychedelic bands who abandoned standard pop or rock traditions in favour of instrumental and compositional techniques more commonly associated with jazz, folk, or classical music, while retaining the instrumentation typical of rock music. Additional elements contributed to its "progressive" label: lyrics were more poetic, technology was harnessed for new sounds, music approached the condition of "art", and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening rather than dancing.

Tarkus is the second studio album by English progressive rock band Emerson, Lake & Palmer, released on 4 June 1971 on Island Records. Following their debut tour across Europe during the second half of 1970, the group paused touring commitments in January 1971 to record a new album at Advision Studios in London. Greg Lake produced the album with Eddy Offord as engineer.
