When Led Zeppelin first emerged, in 1968, New Musical Express scribe Charles Shaar Murray famously hailed their playing style as “Blues on steroids”. Rolling Stone later called them “The heaviest band of all time”, “The biggest band of the Seventies” and “One of the most enduring bands in Rock history”. However, their “adaptations” of various Blues and R&R classics frequently landed them in trouble, for breaches of copyright, which led to several well-publicised court cases. This compilation presents twenty-eight prime examples of Led Zeppelin’s roots, with the emphasis very much on those Blues icons - Muddy Waters, Howlin’ Wolf, Robert Johnson, Otis Rush, Blind Willie Johnson, Sleepy John Estes, etc - whose tunes they played on steroids. Plus, songs they purloined/borrowed from R&R icons like Eddie Cochran, The Johnny Burnette Trio, Little Richard, Bo Diddley, etc.
