Designed to replicate England's teen-targeted pirate radio stations, this 1967 masterpiece is the rock equivalent of Andy Warhol's soup cans. Kitschy jingles and the Who's fake commercials for real products mix with pop tunes about the anxieties of youth ("Tattoo") and troubled relationships ("I Can See for Miles"). The stereo mix showcases choirboy harmonies, while the second disc's mono mix throbs with John Entwistle's meaty bass. A whopping 27 outtakes and alternate versions make this the definitive Sell Out.
