Robert Plant is giving expectant fans a preview of what his forthcoming solo album will sound like, even while he's hinting at another long talked-about reunion. With Led Zeppelin? Most certainly not. Instead, he might be up for a second collaboration with Alison Krauss.

Plant tells Rolling Stone that his forthcoming studio effort, the first since he put out 'Band of Joy' in 2010 is "really a celebratory record, but it’s very crunchy and gritty, very West African and very Massive Attack-y. There’s a lot of bottom end, so it might sound all right at a Jamaican party, but I’m not sure it would sound all right on NPR."

Recorded at Peter Gabriel's Real World Studios, the as-yet unnamed album is set for release on Sept. 9. The sessions featured several contributors from Plant's 2005 project 'Might ReArranger,' as well as more exotic instrumentation: "I've also got this Fulani guy from Gambia [Juldeh Camara] playing one-string ritti," Plant says. "And I'm singing and wailing on top of everything."

A summer tour is set with the Sensation Space Shifters, followed perhaps by another album with Krauss, the bluegrass sensation with whom Plant recorded 2007's 'Raising Sand.' They previously attempted a second album in 2009, with producer Daniel Lanois taking over for T-Bone Burnett, but those sessions stalled. No word on whether Burnett would return for another try at a sophomore Plant-Krauss project.
