Coda

Coda is a rarities compilation album by the English rock band Led Zeppelin. The album is a collection of unused tracks from various sessions during Led Zeppelin's twelve-year career. It was released in 1982, two years after the group had officially disbanded following the death of drummer John Bonham. The word coda, meaning a passage that ends a musical piece following the main body, was therefore chosen as the title.
The fifth Swan Song Records album for the band, Coda was released to honour contractual commitments to Atlantic Records and also to cover tax demands on previous monies earned. It cleared away nearly all of the leftover tracks from the various studio sessions of the 1960s and 1970s. The album was a collection of eight tracks spanning the length of Zeppelin's twelve-year history. Atlantic counted the release as a studio album, as Swan Song had owed the label a final studio album from the band. According to Martin Popoff, "there's conjecture that Jimmy called 'We're Gonna Groove' a studio track and 'I Can't Quit You Baby' a rehearsal track because Swan Song owed Atlantic one more studio album specifically."
Guitarist Jimmy Page explained that part of the reasoning for the album's release related to the popularity of unofficial Led Zeppelin recordings which continued to be circulated by fans: "Coda was released, basically, because there was so much bootleg stuff out. We thought, "Well, if there's that much interest, then we may as well put the rest of our studio stuff out". As John Paul Jones recalled: "They were good tracks. A lot of it was recorded around the time punk was really happening... basically there wasn't a lot of Zeppelin tracks that didn't go out. We used everything.
