NASHVILLE, Tenn. -- Two singers with very different styles will play together at Bonnaroo in 2008.

Led Zeppelin lead singer Robert Plant will take the stage with Bluegrass singer Allison Krauss.

The two made an album together called "Raising Sand,” which was released in October. The album has already sold more than 340,000 copies.

Plant and his other bandmates in Led Zeppelin played their first full concert in decades on Monday night in London.

In addition to their Bonnaroo gig, Krauss and Plant will also tour the U.S. and Europe next year.

The 2008 edition of Bonnaroo is set for June 12 through 15 in Manchester.
