The Coen brothers and T Bone Burnett will celebrate the folk music of their 1960s Greenwich Village drama Inside Llewyn Davis with a concert in New York.
The filmmakers announced that they will host the event on September 29. Joan Baez, Marcus Mumford, Patti Smith, Jack White, Colin Meloy and others will perform.
Several of the film's stars will also perform, including Oscar Isaac, who plays a folk singer struggling to make it in pre-Bob Dylan New York. The film, with music supervised by Burnett, features several authentic performances of lesser-known songs from the late 1950s and early '60s folk revival.
The film opens in the US on December 6.
The Coen brothers and Burnett memorably partnered for the Grammy-winning soundtrack to O Brother, Where Art Thou?
