Outside of the long-running debate about Led Zeppelin getting back together to record some new material, the next best thing could possibly happen. Robert Plant revealed that he has discovered some previously unreleased material from the group that could soon see the light of day.

"I found some quarter-inch spools recently," he told BBC 6. "And there's some very, very interesting bits and pieces that probably will turn up [soon]."

Plant is looking to use the tapes as bonus tracks on the reissues that are expected in 2014. They already have Jimmy Page's approval, but John Paul Jones is particularly interested in making sure that some of them don't wind up on the shelves.

"I'm desperately trying to [use] this one track – or the two tracks – [with] John Paul Jones singing lead," Plant continued. "And so far [Jones is] up to giving me two cars and a greenhouse [to leave] them [off] the album."

That said, Jones may be too busy these days to notice. He is currently working on an operatic adaptation of 'The Ghost Sonata,' a 1908 play by Swedish writer August Strindberg.
