this film: Another day, another time: celebrating the music of 'Inside Llewyn Davis'.
The original film Inside Llewyn Davis (from the team of the Coen Brothers and T-Bone Burnett, who gave us O brother, where art thou?) is set in the New York folk scene of the early 1960s; a plot outline can be found here. From the BIB editor's hazy memories of the time, things could indeed get that complicated, even for people not in New York...
Another day, another time was shot at a concert featuring the Avett Brothers, Joan Baez, the Dave Rawlings Machine, Rhiannon Giddens of the Carolina Chocolate Drops, Lake Street Dive, Colin Meloy, the Milk Carton Kids, Marcus Mumford, the Punch Brothers, Patti Smith, Willie Watson, Gillian Welch, Jack White, and Oscar Isaac. The music played consists of songs from the film and other music of the same vintage.
Update: our Midland Correspondent passes on the news from his Dublin-based son that Another day, another time is soon to be screened at the Light House Cinema in Market Square, Smithfield, Dublin 7. Inside Llewyn Davis was screened at six venues in Ireland last month, according to the Access Cinema website.
