Trailer: the Coen Brothers' 'Inside Llewyn Davis'
Even the trailers for Coen Bros/ films are better than 95% of the movies out there.
Also note that the club he ends up at in the final scene in the trailer is called The Gates of Horn. Does that peg this as a retelling of The Odyssey? But the Coens already did a retelling of the Odyssey featuring musicians, so . . . yeah. This'll be one to watch.
