Over 20 minutes of previously unreleased footage featuring Led Zeppelin performing live at the Pontiac Silverdome in 1977 has surfaced online.

The 8mm footage, synchronized with the original audio, originates from the archives of professional photographer Jim ‘Speedy’ Kelly.

A newly surfaced 23-minute video reveals previously unreleased footage of Led Zeppelin’s live performance at the Pontiac Silverdome in Pontiac, Michigan, on April 30, 1977. The show attracted a record-breaking audience of 76,200 attendees, each paying $10.50 for admission. The footage, now available on a YouTube channel dedicated to the late Jim Kelly, aka ‘Speedy,’ a professional photographer and avid music fan, showcases his 8mm recordings of various concerts in the 1970s, featuring artists like Van Halen, Alice Cooper, Yes, Queen, Rush, and Pink Floyd.

Collaboratively, the Pontiac footage underwent digital transfer by the Genesis Museum, known for their work on Genesis’s 1973 Shepperton Studios set’s 4K remaster. The production efforts were led by Genesis enthusiast ikhnaton, while film restoration and synchronization with bootleg audio were accomplished by two well-known figures in the Led Zeppelin collectors’ community, Etienne and LedZepFilm.

LedZepFilm explains, “Typically, I rely on the audio source as the definitive guide and synchronize the film accordingly. Occasionally, I might make adjustments to the audio if it seems too fast or slow to my perception and proceed from there. Various clips may require different adjustments. However, it’s worth noting that achieving 100% accuracy in speed is challenging due to the analog nature of both sources.”

It’s important for viewers to be aware that although film cameramen are visible around the stage, the presence of these individuals does not guarantee the existence of additional, more official footage in the Jimmy Page archive. The cameramen were part of the production team from Worldstage, tasked with projecting live footage of the band onto the large video screen above John Bonham’s drum kit. However, there is a belief that this particular footage was not preserved or saved for future use.
