At a time when listeners increasingly download or upload songs, creating personal playlists on MP3 players and I-Pods, the art of packaging music seems to be fading away. But, for more than 50 years, musicians have released their work inside brilliantly-designed packages that made an important statement about their music and style. Look at the cover of Sgt. Pepper’s Lonely Heart Band, for example—just one of the 500 memorable images in this amazing collection, all chosen by a panel of 50 experts and each accompanied by enlightening commentary. Among the choices: the brilliantly psychedelic and way-out art from the Rolling Stones’ Their Satanic Majesties Request; Peter Tosh’s fiery cover for Bush Doctor; and the somewhat demented-looking prom queen on Hole’s Live Through This album. From rock to pop, jazz to blues, these are all artistically, stylistically, and culturally significant in their own way, and will undoubtedly spark a debate with fans around the world.
