Led Zeppelin frontman and lead vocalist, Robert Plant, has recently stumbled upon some "hidden gems" from the band's 1990 remastered catalogue. In an interview with BBC Radio 6, which will only be available to stream online through October 23rd, Plant told the DJs Radcliffe and Maconie, "I had a meeting with Jimmy [Page] and we baked 'em up and listened to 'em. And there's some very, very interesting bits." Some of the more interesting unreleased material includes a handful of recordings with the band's bassist, John Paul Jones, on lead vocals. Speaking to the quality of his own voice, JPJ jokingly offered Plant "two cars and a green house" to leave that material unreleased.
According to Plant, the band did not record many additional tracks when they were making albums, but did record "different versions of things, different approaches to the mixes." In an interview with Rolling Stone, Zeppelin guitarist Jimmy Page noted that they had experimented with different equipment in different locations, constantly searching for the right sound. For example, the drums for "When the Levee Breaks" were recorded in a hallway to achieve a heavier, room-filling quality. Take a listen below.
There is no release date set for the catalogue, but Page revealed that the band will be very selective in choosing the bonus material to be released. "I'm not just throwing on any old flotsam and jetsam. This will be really substantial stuff."
