Led Zeppelin will release The Complete BBC Sessions, an updated version of the 1997 BBC Sessions, on September 16. The collection is taken from the band’s BBC radio appearances between 1969 and 1971.

The new version of the release will feature newly remastered audio and eight unreleased recordings from the sessions, including three taken from a “lost” 1969 recording. The collection will be available in a 3CD or 5LP version, along with a digital download version. The remastering of the tracks was overseen by Jimmy Page, who produced all of the legendary band’s studio albums.

In an interview with Guitar World, Page spoke about the sessions, saying, “The BBC Sessions show in graphic detail just how organic the group was. Led Zeppelin was a band that would change things around substantially each time it played. We were becoming tighter and tighter, to the point of telepathy.”
