Another Day, Another Time: Celebrating the Music of "Inside Llewyn Davis," a one-night-only concert, was held at New York City’s Town Hall in September to celebrate the music of the film Inside Llewyn Davis. The evening was filmed for a documentary that receives its broadcast premiere on SHOWTIME tonight at 10 PM. Nonesuch Records will release a live album from the concert in late winter/early spring 2014 (details to follow soon). The concert, documentary, and live album were produced by Inside Llewyn Davis writer/director/producers Joel and Ethan Coen and soundtrack producer T Bone Burnett.

Tonight’s documentary features performances from the film’s star, Oscar Isaac, as well as The Avett Brothers, Joan Baez, Rhiannon Giddens, Colin Meloy, The Milk Carton Kids, Marcus Mumford, Punch Brothers, Dave Rawlings Machine, Patti Smith, Gillian Welch, Willie Watson, Jack White, and more, plus behind-the-scenes material and interviews with the filmmakers and cast.

"Picture a parade of superb classic and contemporary folk, roots, and rock musicians playing in your living room and you’ll have some idea of the cozy feel of the concert film," raves the Boston Globe's Sarah Rodman. The documentary, says the Hollywood Reporter, “well captures the highlights of one of the year’s finest concerts.”

Another Inside Llewyn Davis star, John Goodman, who emceed the Town Hall concert, will put those skills to good use this weekend as he hosts Saturday Night Live on NBC, marking his lucky 13th time as host of the show.

Inside Llewyn Davis opened in select theaters in New York and Los Angeles last weekend and expands to more theaters across the United States next weekend.
