O Brother, Where Art Thou?, country’s top-selling album for 2001, has a Grammy nomination for album of the year, and the award-winning project generated a number of spinoff nominations in other categories.

Jo Dee Messina, Diamond Rio and Steven Curtis Chapman announced Grammy nominees Friday morning (Jan. 4) in Nashville during a news conference held simultaneously with a similar event in Los Angeles. The Grammys are scheduled for Feb. 27 at Staples Center in Los Angeles and will be broadcast live by CBS.

Perhaps the biggest surprise of the day, in country categories, was the multiple nominations earned by the Hank Williams tribute album, Timeless. Performances from that project by Sheryl Crow, Lucinda Williams, and Johnny Cash picked up nominations, and the album is up for best country album.

O Brother producer T Bone Burnett is nominated for producer of the year, non-classical, and Ralph Stanley’s haunting performance of “O Death” from the soundtrack is up for best male country vocal performance.

“I Am a Man of Constant Sorrow” as performed by The Soggy Bottom Boys -- Dan Tyminski, Harley Allen and Pat Enright -- is up for best country collaboration with vocals. Another O Brother performance is nominated in the same category, “Didn’t Leave Nobody but the Baby,” by Emmylou Harris, Alison Krauss and Gillian Welch.

O Brother, Where Art Thou? is not nominated for best country album, Grammy officials explained, because it is nominated for best compilation soundtrack album for a motion picture, television or other visual media.

Krauss, with her band Union Station, also has nods for best country performance by a duo or group with vocal, for “The Lucky One”; best country instrumental performance, for “Choctaw Hayride”; and best bluegrass album, for New Favorite. Robert Lee Castleman’s “The Lucky One” is nominated for best country song. New Favorite also is up for best engineered album, non-classical. The award would go to engineer Gary Paczosa.
