Before the Coen Brothers' film, 'Inside Llewyn Davis,' hit theaters last year, the directors and their musical guru, T Bone Burnett, put together a massive concert in honor of the movie. Hosted at New York City's iconic concert venue Town Hall, 'Another Day, Another Time: Celebrating the Music of 'Inside Llewyn Davis'' featured the likes of the Avett Brothers (above), Conor Oberst, Colin Meloy, Jack White, Marcus Mumford, Oscar Isaac and a whole lot more.

Some of the selections during the performance came directly from the movie (the soundtrack was produced by Burnett), while others were original tracks or traditional folk songs inspired by the movie. For fans who weren't lucky enough to witness the once-in-a-lifetime concert first-hand, Showtime captured the event and turned it into a documentary.

Nonesuch Records has announced plans to release the soundtrack to the Town Hall concert; it was initially set to hit store shelves earlier this year, but for unknown reasons, it's been delayed -- the official release date is Jan. 13, 2015. Fans can pre-order the two-CD or triple-LP editions of the soundtrack via Nonesuch -- for a limited time, all pre-orders will come bundled with a 13"x23" limited-edition poster from the concert. Get details on the release here.
