Ten months after playing their first full-length concert in almost three decades, members of legendary rock group Led Zeppelin [ tickets ] appear poised to mount a full-blown tour--with one catch: frontman Robert Plant won't be participating.

According to the BBC News, bassist John Paul Jones, while speaking at a guitar show in the UK, said that he, guitarist Jimmy Page and drummer Jason Bonham (son of original Zeppelin drummer John Bonham, who died in 1980), plan to record and tour with a yet-to-be-named vocalist, and that the group is "trying out a couple singers."

"We want to do it," Jones reportedly said. "It's sounding great and we want to get on and get out there."

Jones went on to say that the group isn't looking for a Plant clone.

"It's got to be right," he said. "There's no point in just finding another Robert. You could get that out of a tribute band, but we don't want to be our own tribute band.

"There would be a record and a tour, but everyone has to be on board," he added.

Last December, Plant, Page, Jones and Bonham performed a one-off concert at London's O2 arena as part of a tribute to the late Ahmet Ertegun, who founded the group's longtime label, Atlantic Records. The performance received high praise from fans, critics and other members of the music industry, and many felt the quartet would mount a reunion tour soon after.

However, despite the apparent demand for the group to hit the road, Plant instead opted to spend most of this year focusing on his collaborative album with Allison Krauss, "Raising Sand." The pair recently wrapped up their tour in support of the set.

According to Billboard, Page, Jones and Bonham have been rehearsing together in recent months in the hopes that Plant would ultimately sign on for a full-fledged reunion. Alter Bridge vocalist Myles Kennedy is rumored to be one of the singers in contention for the slot.

On Nov. 4, Rhino Records will mark Led Zeppelin's 40th anniversary with the release of "Led Zeppelin Definitive Collection Mini LP Replica CD," a limited-box set that will contain all 10 of the group's albums in mini-LP replicas featuring artwork from the original UK versions of the vinyl-LP sleeves. More information about the forthcoming set is posted at Rhino's website.
