Country music reclaimed its traditional soul with the chart-topping triumph of the O Brother, Where Art Thou? soundtrack. This concert sequel, recorded (and filmed) at Nashville's venerable Ryman Auditorium, reunites Emmylou Harris, Gillian Welch, Alison Krauss and Union Station, and other O Brother standouts. With little duplication, the selection extends the movie's revival of acoustic spirituals and Appalachian balladry, though the performances and pacing of the concert aren't quite as consistently compelling as the studio soundtrack. Among the highlights are a pair of originals by Welch and David Rawlings, the bluesy "Dear Someone" and the Everlyesque "I Want to Sing That Rock and Roll." Where O Brother interspersed archival recordings among the contemporary artistry, the concert finds Nashville gospel's Fairfield Four harmonizing on the chain-gang chant of "Po' Lazarus," while the late John Hartford (in one of his final performances) renews the deadpan whimsy of "Big Rock Candy Mountain." --Don McLeese
