One of the truly seminal bands of British hard rock, Led Zeppelin took the structures of the blues, married it to the volume and impact of rock & roll, and created a hybrid that's been a major influence on literally thousands of hard rock and heavy metal bands ever since. A to Zeppelin: The Story of Led Zeppelin is an unauthorized documentary that examines the history and legacy of this most important group. The film includes interviews with road manager Richard Cole, touring partner Carmine Appice, producer Andy Johns, close friends Pamela Des Barres and Lori Mattix, and fans and compatriots from Bad Company, Foreigner, and the Yardbirds. Please note that this film was created without the participation of Led Zeppelin or their representatives, and features no music or performances from the band.
