August 31: Marcus Mumford of Mumford and Sons performs at the Gentlemen of the Road Stopover at Troy Memorial Stadium in Western Ohio.

Hear the duo's song from the Coen brothers' folk film soundtrack.

The first song from "Inside Llewyn Davis" has emerged.

For the upcoming film, the Coen brothers turned their directorial vision toward New York's early 1960s folk scene, prompting an anticipated soundtrack and now, a lead track: Marcus Mumford and Oscar Isaac's take on "Fare Thee Well (Dink's Song)."

The Mumford & Sons frontman and the film's titular star offer a tender, harmonized version of the traditional song, keeping the instrumentation simple and acoustic. The soundtrack, produced by T Bone Burnett, also features contributions from stars Justin Timberlake and Carey Mulligan, the Punch Brothers, Dave Van Ronk and Bob Dylan, who knows a thing or two about the glory days of Greenwich Village.

"Inside Llewyn Davis" is due Dec. 20, with the soundtrack set for a Nov. 12 release. The Coens and Burnett will present a live version this Sunday with their "Another Day Another Time" concert, which will cover the film's music and its inspirations and feature performances from Mumford, Jack White, Joan Baez, the Avett Brothers, Colin Meloy and many more.
