Very few Led Zeppelin performances were caught on camera during the band's life-span, but the footage that has been preserved for posterity is collected on this release. With a running time of over five-and-a-half hours, this is the definitive word on Zep's global stage-straddling performances. The footage is taken from London's Royal Albert Hall in January 1970, London's Earls Court in May 1975, Knebworth in August 1979, and Madison Square Garden in July 1973. Guitarist Jimmy Page has taken great care to restore, remix, and remaster the sound from these shows, providing a visual and sonic assault that offers indisputable proof of Led Zeppelin's reputation as a rock & roll behemoth. Additional footage comes in the shape of several television interviews, a bootleg shot of the band performing "Heartbreaker," behind the scenes footage from Knebworth, and a whole lot more.
