Directed by Jimmy Page, it took a year of intensive research to assemble this five-and-a-half-hour digital re-tooling of the Zeppelin legend. Previously, the only officially-sanctioned live footage was the 1976 film The Song Remains The Same. Here, a trawl of the band's own unreleased archives combines with reclaimed bootleg material to tell the Zep story in chronological fashion, via 30 performances from four memorable concerts—the Albert Hall (1970), Madison Square Garden (1973), Earls Court (1975) and Knebworth (1979).
