Which Pink Floyd album features a lone cow on the cover?

Atom Heart Mother is the Pink Floyd album featuring a lone cow on its cover.

Released in 1970, it was the band’s fifth studio album and their first UK number-one album. The original sleeve showed a Holstein-Friesian cow standing in a field, with no album title, band name, or other identifying text.

The striking image was created by Hipgnosis, the design collective responsible for many iconic Pink Floyd covers. Photographer Storm Thorgerson reportedly drove into the countryside near Potters Bar and photographed the first suitable cow he encountered. The cow was later identified as Lulubelle III.

The cover reflected Pink Floyd’s desire to move away from the psychedelic imagery associated with their earlier work. It is sometimes confused with the unofficial compilation The Dark Side of the Moo, whose title and artwork also reference a cow, but that is not a Pink Floyd studio album. The album’s title track is a lengthy experimental suite co-written with composer Ron Geesin.
