Unheard Led Zeppelin recordings unleashed

Two previously unheard recordings were unveiled by the legendary rock group Led Zeppelin before the reissue of the band's first three albums in June.

Blues classic Keys to the Highway, recorded in 1970, and an early version of the famous song Whole Lotta Love will now be heard for the first time.

"I don't want to die and have somebody else do it," guitarist Jimmy Page says about the upcoming reissues. "I'm authoritative about what was done in the first place." The new material "deserves to be heard" because "it's performance art" he added.

"It was a particularly prolific time, where we were learning about each other's capabilities. Jimmy and I were just fooling around with the stuff that we would play at home. We were just trying things out. Nothing was premeditated" says singer Robert Plant.

"It's undeniable that we're good, the band was the real deal." Page added.

"My enthusiasm sometimes got in the way of finesse. I listen to it and go, wow, why didn't I shut up a bit? I kind of overcooked it" Robert Plant, 65, laughed.

Led Zeppelin remains intense until today, even though they broke up in 1980, following the death of the drummer John Bonham.
