Animals is the tenth studio album by English progressive rock group Pink Floyd. Released in January 1977, Animals is a concept album that provides a scathing critique of the social-political conditions of 1970s Britain, and presents a marked change in musical style from their earlier work. Animals was recorded at the band's studio, Britannia Row, in London. Production of the album was punctuated by the early signs of discord that several years later would culminate in keyboardist Richard Wright leaving the band. The album's cover image, a pig floating between two chimneys on Battersea Power Station, was designed by bassist and writer Roger Waters, and produced by long-time collaborator Hipgnosis.
The album was released to mixed reviews in the UK, where it reached number two. It was also a success in the US, reaching number three on the Billboard album charts. Although it scored on the American charts for only six months, steady sales have resulted in the album being certified four times platinum by the RIAA. The size of the venues on the band's In the Flesh tour, and an incident where the behaviour of fans prompted Waters to spit at one of them, prompted the bassist to write the band's subsequent studio album, The Wall.
