Which 2013 Coen brothers film follows a folk singer navigating the Greenwich Village scene?

The 2013 Coen brothers film about a folk singer navigating Greenwich Village is Inside Llewyn Davis.

Set in New York in 1961, the film follows Llewyn Davis, played by Oscar Isaac, through a difficult week of couch-surfing, unpaid debts, strained relationships, and uncertain musical prospects. He performs at Greenwich Village clubs but cannot turn his talent into a stable career.

The fictional Llewyn was partly inspired by folk musician Dave Van Ronk and the Greenwich Village scene described in Van Ronk's autobiography. The film's music was treated seriously: many performances were recorded live and sung in full, with T Bone Burnett serving as executive music producer.

Joel and Ethan Coen wrote, directed, produced, and edited the film. It premiered at the 2013 Cannes Film Festival, where it won the Grand Prix. Although it received acclaim and earned Oscar nominations for cinematography and sound mixing, it was not nominated for Best Picture. A related point of confusion is that the movie is inspired by the folk revival, but Llewyn Davis himself is a fictional character.
