Emmylou Harris, Rodney Crowell and Richard Thompson's new tour, which kicks of in the D.C. area Friday, has got to be one of the hottest tickets this year.

There is little doubt the tour, which matches three legendary performers who got their start in about the same period between the late '60s and early '70s, will not run out of material for audiences as it winds its way through various cities.

"The only problem we have is that we have almost too many songs to draw from," said Crowell of the set he and Harris will perform, yet it could well apply to Thompson and his rich catalog. "We will do [the title track of our new duets album] 'Old Yellow Moon,' and we'll do songs from way back and songs from just the other day. We could do a show every night and not run out of new material."

Americana fans won't doubt that statement. Harris is, of course, the 12-time Grammy Award-winning musical icon who made her name playing clubs in the D.C. area after she couldn't gain traction in Nashville. A protegee of Gram Parsons, Harris and her Hot Band have recorded some of the most well-known folk and country-rock songs in recent history, including the Crowell-penned "Leaving Louisiana in the Broad Daylight."

Crowell, a legendary Nashville songwriter, met Harris in the D.C. area soon after she recorded his song "Blueberry Wine" for her 1975 major-label debut, "Pieces of the Sky." He also played in Harris' Hot Band for three years before moving on to his solo work.

And Thompson is the legendary singer-songwriter and guitarist who started his career as a teenager with the British folk legends Fairport Convention before moving on to record with his now ex-wife, Linda Thompson, and then as a solo artist. He is consistently hailed as one of the best guitarists in the world, most recently after the release of his Buddy Miller-produced album, "Electric."

Crowell chuckled when talking about the band he and Harris assembled for the album and the tour.

"I think they already knew most the songs," he said, noting some of the classics that the duo plays, although the set list changes frequently. "It happens in a strange way, how that works. It's very [contingent] on the atmosphere, on the crowd."

While a set list may vary, it's a good bet that Harris, Crowell and Thompson will only deliver musical home runs.
