While I'm on the trail, let me shamelessly plug the upcoming Coen Brothers movie, which sounds utterly irresistibly to folk music lovers.
Some say it's good (from a review at Cannes via The Playlist):
Arguably the least plot driven film from the Coens since "The Big Lebowski," which still provided the journey for a new carpet as the Macguffin of sorts, "Inside Llewyn Davis" is even more freeform, but never out of the Coens' grasp. The film unfolds over what turns about be roughly a week or so in the life of Llewyn, and follows his attempts to put some order to the chaos in his life. And it's a tough week: Jean reveals he's pregnant with his child; he's saddled carrying the Gorfeins' cat after it escapes out the door, and accidentally locks the door behind him after staying the night (a great running gag that eventually turns into a lovely metaphor for Llewyn's journey); he's chasing payments from Legacy and trying to line up some gigs. A road trip later in the picture offers a change of pace, but this is a slice of life of one of many trying to make it on the folk circuit, and the Coens capture every detail, acknowledging their fondness for their era, while being able to laugh at it as well (though without getting as broad as Christopher Guest's "A Mighty Wind," the last major folk movie).
Gotta love that classic folk song, produced by the irresistible T-Bone.
