Tarkus is the second studio album by English progressive rock band Emerson, Lake and Palmer, released on 14 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.
