Music from O Brother, Where Art Thou?

In a quirky retelling of Homer's The Odyssey, this recent movie from Joel and Ethan Coen is set in Mississippi in 1937. The musical style is early country/folk/bluegrass, and Michael Brown's concert band setting is unique and inviting. Includes: Down to the River to Pray, I Am A Man of Constant Sorrow, Keep on the Sunny Side, and I'll Fly Away. For added flavor, use the optional guitar/banjo parts.
