An expert analysis of Zep's most revered record with rare and classic performances, interviews, seldom seen photographs and contributions from those involved. This DVD is a documentary film about the build-up, making, release, and - crucially - music contained on this most revered of albums. With the aid of rare and classic performances, scarce interviews, seldom seen photographs and contributions from those involved in the making of the record - plus the review and critique from a panel of Zeppelin experts - this program finally lifts the lid on what many believe to be Led Zep's very finest offering. With contributions from; the album's engineer, Ron Nevison; former Yardbird, Chris Dreja; Swansong recording artist, Maggie Bell; author of The Rough Guide to Led Zeppelin, Nigel Williamson; Tight But Loose editor, Dave Lewis; Classic Rock Magazine's Malcolm Dome; renowned guitar tutor and author, Rikky Rooksby and Robert Plant biographer, Neil Daniels. This is the complete story behind what what Rolling Stone called "their Tommy, Beggar's Banquet and Sgt. Pepper rolled into one".
