“Meddle” is Pink Floyd’s sixth studio album, released in 1971. It was produced between the band's touring commitments, from January to August 1971. The album was recorded at a series of locations around London, including Abbey Road Studios and Morgan Studios. With no material to work with and no clear idea of the album's direction, the group devised a series of novel experiments which eventually inspired the album's signature track, "Echoes". Although many of the band's later albums would be unified by a central theme with lyrics written mainly by Roger Waters, Meddle was a group effort with lyrical contributions from each member, and is considered a transitional album between the Syd Barrett-influenced group of the late 1960s and the emerging Pink Floyd. The cover, incorporating a close-up shot of an ear underwater was, as with several previous albums, designed by Hipgnosis.
