Jimmy Page and Robert Plant have both been in the studio recently, for very different projects.

Jimmy Page and Robert Plant have both been in the studio recently, for very different projects.

Page has been in a London studio re-mastering all of the band's albums. The work on the albums isn't that surprising, as Page told Mojo magazine last month that Zep were going to reissue their Complete Studio Recordings box -- which was first released in 1993 -- with additional unreleased tracks. Page first re-mastered the band's catalog for that box set and when each album was reissued individually in 1994.

Robert Plant recently added vocals to the next album by British band Primal Scream. Plant says, "I sang a bit on the Primals stuff because I think their references on looking back on the glorious past and the way they bring them into the contemporary world are fantastic."
