The soundtrack to the 2000 Coen brothers’ film was recorded before the movie was even filmed because it played such an integral role in the plot. The best-selling record won three Grammys, including Album of the Year and Best Male Country Vocal Performance for the song “O, Death” by Ralph Stanley. While the record is rife with other somber songs like “Lonesome Valley” and “I am a Man of Constant Sorrow,” it also sports some upbeat tunes like “Keep on the Sunnyside.” In addition to Stanley, other musicians who performed on the soundtrack include Alison Krauss, Emmylou Harris, and Norman Blake.
