Just before his death in 2013, musician, poet and iconoclast Lou Reed teamed up with legendary photographer Mick Rock on a book of intimate, never-before-scene pictures. Called Transformer after Reed’s groundbreaking 1972 album of the same name—with a cover shot my Rock—the collection is a portrait of the Velvet Underground genius at the height of his creative powers through the ’70s, offering intimate views in the studio, performing onstage, relaxing at home, or spending time with fellow luminaries Andy Warhol, David Bowie and Mick Jagger.
