On the heels of a half-dozen associated Grammy Awards recognizing the "O Brother, Where Art Thou?" soundtrack phenomenon, the Down From the Mountain tour it inspired will hit the road again this summer. Although routing of cities and venues is not yet been confirmed, the five-week amphitheater tour is scheduled to kick off June 25. Full details are expected in the coming weeks.

As with the first version of the acclaimed bluegrass and roots music tour, which visited 17 cities through January and February, the bill will consist of Alison Krauss & Union Station featuring Dan Tyminski, Emmylou Harris, Patty Loveless, Ralph Stanley, the Del McCoury Band, Norman & Nancy Blake, the Nashville Bluegrass Band, the Whites, and Jerry Douglas. The summer run will also add Ricky Skaggs to the lineup.

The Lost Highway/Mercury Nashville "O Brother" set yielded an avalanche of Grammys last night (Feb. 27), including the coveted album of the year award and the best compilation soundtrack album for a motion picture, television, or other visual media.

As the Soggy Bottom Boys, Union Station members Dan Tyminski and Pat Enright (along with Harley Allen) won the best country collaboration with vocals award for "I Am a Man of Constant Sorrow" from the "O Brother" collection, while the male country performance honor went to Ralph Stanley's soundtrack version of the traditional "O Death." T Bone Burnett, who steered the compilation, won producer of the year honors for his work on the soundtrack, the "Down From the Mountain" live album (winner of the best traditional folk album Grammy), and wife Sam Phillips' "Fan Dance" (Nonesuch).

In addition, Krauss & Union Station are basking in the glow of a trio of Grammys themselves. Their Rounder album "New Favorite" nabbed best bluegrass album honors, while album track "The Lucky One" was deemed best country performance by a duo or group with vocals. "Lucky" also won the best country song honor for songwriter Robert Lee Castleman.

As previously reported, Krauss & Union Station will themselves hit the road for a 15-date trek that kicks off March 21 in Detroit and wraps April 27 with an appearance at the annual Merle Watson Festival ("Merlefest") in Wilkesboro, N.C.

"O Brother, Where Art Thou?" is No. 2 in its 64th week on Billboard's Top Country Albums chart, where it has logged 26 of those non-consecutive weeks in the No. 1 position. The album is No. 15 on The Billboard 200, and has sold 4 million copies in the U.S. to date, according to SoundScan.
