Also in 2000, Harris joined an all-star group of traditional country, folk and blues artists for the T-Bone Burnett–produced soundtrack to the Coen Brothers film, "O Brother, Where Art Thou?" The soundtrack won multiple CMA, ACM and Grammy awards. A documentary/concert film, "Down from the Mountain", featured the artists performing music from the film and other songs at the Ryman Auditorium. Harris and many of the same artists took their show on the road for the Down from the Mountain Tour in 2002. In 2003, Harris supplied the finishing touches in harmonizing with the Dixie Chicks on a song they were recording in the studio, "Godspeed".
