Hailed by critics and embraced by fans to the tune of nine million copies sold since its release, the multi-award-winning soundtrack album, 'O Brother, Where Art Thou?,' will celebrate its tenth anniversary with a deluxe two-CD set, due August 16.

A total of 17 new tracks will be available, in addition to the original disc which featured 19 old-time, bluegrass and country tunes by such artists as Alison Krauss, Gillian Welch, Ralph Stanley, the Cox Family, and of course, Dan Tyminksi, whose vocal rendition of 'Man of Constant Sorrow' was lip-synched by George Clooney in the critically-acclaimed Coen Brothers film. That tune also featured vocals by Pat Enright and the now-late Harley Allen (as the Soggy Bottom Boys).

Thirteen of the newly-released songs were recorded during the original sessions for the film, and with the exception of 'Cow Road' (by T Bone Burnett) and 'I'll Fly Away' (performed by the Kossoy Sisters) went unheard on-screen. This will mark the first time these tracks have been available in any format.

In spite of receiving very little radio airplay, 'O Brother' became one of the 10 best-selling soundtracks of all time. It's also the top-selling soundtrack and the 17th biggest album of the 21st century. The deluxe edition features original producer, 12-time Grammy winner (and Oscar winner), T Bone Burnett personally involved in all aspects of this expanded version's release.

The second disc of the 'O Brother, Where Art Thou?' Deluxe Edition features artists who appeared on the original album (John Hartford, Norman Blake, the Fairfield Four, the Cox Family and the Peasall Sisters) plus a few who didn't (Colin Linden, Alan O'Bryant, Ed Lewis and Van Dyke Parks). The disc's previously recorded tracks include two from Duke Ellington, along with 'Tom Devil' by Ed Lewis and the Prisoners, and the Kossoy Sisters' 'I'll Fly Away.'.

In addition to the Grammy win for Album of the Year and two other Grammy awards that year, 'O Brother' gave birth to a groundbreaking Nashville concert, which resulted in the documentary film, 'Down From the Mountain,' and a sold-out U.S. tour. That album also won a Grammy.
