Legendary rock band Led Zeppelin is celebrating 40 years since the release of their double album Physical Graffiti. To commemorate the album’s anniversary, guitarist Jimmy Page remastered a deluxe version of Physical Graffiti. Physical Graffiti was the band’s first release on their own Swan Song Records label, which had been launched in May 1974. Until this point, all of Led Zeppelin’s albums had been released on Atlantic Records. The album was a commercial and critical success, having built up a huge advance order, and when eventually released it reached No. 1 on Billboard‘s Pop Albums chart. It has since proven to be one of the most popular releases by the group, shipping 8 million copies in the United States alone (which has made it 16 times platinum as it is a double album). Physical Graffiti was the first album to go platinum on advance orders alone. Shortly after its release, all previous Led Zeppelin albums simultaneously re-entered the top-200 album chart. This is a deluxe 3CD package of Led Zeppelin’s sixth album, with the original album on CD’s 1 and 2 and a companion disc with previously un-released studio outtakes in a new sleeve.
