Led Zeppelin bootleg recordings

The Led Zeppelin bootleg recordings are a collection of audio and video recordings of musical performances by the English rock band Led Zeppelin which were never officially released by the band, or under other legal authority. The recordings consist of both live concert performances and outtakes from studio sessions conducted by the band. Many hundreds of Led Zeppelin bootlegs exist, and are widely collected by fans.

Led Zeppelin were, throughout the decade of the 1970s, one of the world's most frequently bootlegged performers, and to this day remain one of the most bootlegged artists in the history of rock music. In August 1999, the band topped the list of Britain's most bootlegged musicians with 384 bootleg titles, compiled by the Anti-Piracy Unit of British Phonographic Industry. This phenomenon was due partly to the popularity of the band, which has ensured a large and enthusiastic market for unauthorised recordings, and partly to the large size of the audiences who attended their performances, which made the effective detection of covert recording equipment at these concerts virtually impossible.

Led Zeppelin's manager, Peter Grant, sometimes took extraordinary measures to combat the practice of live bootleg recordings at Led Zeppelin concerts. He is reported to have personally visited record stores in London which were selling Led Zeppelin bootlegs and demanded all copies be handed over. He also monitored the crowd at Led Zeppelin concerts so as to locate anything which resembled bootleg recording equipment. At one concert at Vancouver in 1971 he saw what he thought was recording equipment on the floor of the venue and personally ensured that the equipment be destroyed, only to find out later that the equipment was a noise pollution unit being operated by city officials to test the volume of the concert. Similarly, at the Bath Festival in 1970, he personally threw a bucket of water over unauthorised recording equipment.

These efforts were not enough to prevent the release of a flood of Led Zeppelin bootlegs from the 1970s onwards. As is explained by Led Zeppelin archivist Dave Lewis:
