Ghost in the Machine is the fourth album by The Police, released in 1981 (see 1981 in music). Much of the material in this album was inspired by Arthur Koestler's The Ghost in the Machine, which also donated the title. The cover art for Ghost in the Machine features an LED graphic that depicts the heads of the three band members each with a distinctive hair style (from left to right, Andy Summers, Sting with spiky hair, and Stewart Copeland with a fringe); the band was unable to decide on a photograph to use for the cover.
