who sings man of constant sorrow o brother where art thou
O Brother, Where Art Thou? (soundtrack) "I Am a Man of Constant Sorrow" has five variations: two are used in the film, one in the music video, and two in the soundtrack. Two of the variations feature the verses being sung back-to-back, and the other three variations feature additional music between each verse.[8] The voices of the Soggy Bottom Boys were provided by Dan Tyminski (lead vocal on "I Am a Man of Constant Sorrow"), Nashville songwriter Harley Allen, and the Nashville Bluegrass Band's Pat Enright.[9]
O Brother, Where Art Thou? The film is set in 1937 rural Mississippi[4] during the Great Depression, and its story is a modern satire loosely based on Homer's epic poem The Odyssey that incorporates mythology from the American South. The title of the film is a reference to the 1941 film Sullivan's Travels, in which the protagonist is a director who wants to film O Brother, Where Art Thou?, a fictional book about the Great Depression.[5]
