As it prepares for the November 19 release of the "Celebration Day" CD, DVD and Blu-ray, Led Zeppelin is sprucing up its catalog for a major overhaul and re-release campaign in 2013. Guitarist Jimmy Page tells Britain's Mojo magazine that he's been going through the vaults for material to add to new editions of the band's albums, noting that "there are different versions of tracks that we have that can be added to the album so there will be box sets of material that will come out, starting next year. There will be one box set per album with extra music that will surface." Page's manager Peter Mench told the London Sunday Times these will be "21st-century versions" of the albums, with outtakes, demos and unreleased songs. No release dates have been set yet, however...In other Zep news, singer Robert Plant announced that he's done some recording with the British band Primal Scream for its new album, which is due out next year. Plan previously worked with Primal Scream on its 2002 album "Evil Heat," playing harmonica on the song "The Lord is My Shotgun."
