If hard rock pioneer Led Zeppelin's reunion was a pleasant surprise for devout fans, the latest news is potentially a dream come true. That's right: It seems the quartet are working on material that could form a new album, the band's first of original songs since 1979's In Through the Out Door. But there's just one problem: Frontman Robert Plant has yet to join the sessions.

"I've been working with Jimmy and John Paul and trying [out] some new material," drummer Jason Bonham, the son of original Zeppelin sticksman John, told Detroit's 94.7 WCSX. "I don't know what it will be, but it will be something. At the moment, all I know is I have the great pleasure to go and jam with the two guys and start work on some material."
