ROBERT PLANT and ALISON KRAUSS met at the Crossroads in Lebanon to embark on a memorable musical journey stretching from the Louisiana swamps and Mississippi Delta to the hills of West Virginia and blues clubs of Chicago.

Plant, 59, and Krauss, 36, who will release their soulful album Raising Sand on Tuesday (October 23rd), taped an episode of CMT Crossroads on Thursday at The Mill at Lebanon that will air at a later date.

"To say this is the hottest ticket in town is an understatement," said Bill Flanagan, the show's executive producer. "We've had Nobel Peace Prize winners calling trying to get in here tonight."

Al Gore may not have gotten his ticket, but the audience did include JOHN WAITE, JESSICA SIMPSON, HOLLY WILLIAMS, MICHELLE BRANCH, BARBARA ORBISON, ED KING and BILL LLOYD.

"This is the most important show I think we've ever done," Flanagan said.

Standard format descriptions fail to accurately describe the collaboration, which blended rock, bluegrass, blues, folk, country and other genres into a sound all its own. A blend of everything from LED ZEPPELIN to the EVERLY BROTHERS, it was both timeless and reminiscent of decades ranging from the 1950s to early 2000s.

"Perfection" was a word used by one audience member to describe the music turned out by band leader T-BONE BURNETT, guitar player Buddy Miller, guitarist Marc Ribot, drummer Jay Bellerose and bassist Dennis Crouch.

Although Plant is best known as the lead singer of Led Zeppelin, as a solo artist he has dedicated himself to the international exploration of sounds, rhythms and styles. To be sure, the famous voice is the same, but he's a different man than the hip-hugger-clad golden god who dominated rock music in the '70s. His voice reflects the nuances of a life long-lived, one that has delved into the shadows that accompany fame and loss.

His music still has an overpowering sexuality, but the fast, hard-driving music of his youth has been replaced with a mature, seductive delivery. His coos of "baby" are now more romantic than passionate.
