The Led Zeppelin Deluxe Edition is a series of albums reissued by English rock group Led Zeppelin, distributed by Atlantic Records. It contains all nine of the original Led Zeppelin studio albums remastered from the original analog tapes. Along with the remastered albums, there is a companion disc with each album, consisting of previously unreleased audio tracks and alternate mixes of released tracks. Many of these are described as work-in-progress or alternate mixes made during the original production rather than new remixes generated to highlight discarded recording elements (as did the remixes made for The Beatles Anthology). The first companion album consists of the 10 October 1969 concert in Paris. The albums were released in chronological order, each with inverted album covers.
