Punch Brothers predictably good as usual, rest of 'em so-so. Basically The Folk Revival Part Four: a live concert and rehearsal footage featuring various musicians from the Llewyn Davis soundtrack, and a few stunt castings like Joan Baez and Patti Smith. Chris Thile, the mandolin wiz, is always worth hearing - in moderation, but the problem with the music is exemplified by Marcus Mumford, who has the wardrobe of a 1950's hobo but has a sleek double chin and the phoney voice of someone who has grown up listening to phoney singers and doesn't know any better. He whines and squeaks like Woody Guthrie's peevish kid brother but he's English; if he could sing with genuine emotion it wouldn't matter, but he can't. Most actors don't sing well, and most singers don't act well. Marcus Mumford does neither well.

Chris Thile attempts Luke Kelly, fails, and turns 'The Auld Triangle', a bitter, sleazy truculent prison song into a cheeky little joke number.

A high standard of musicianship among these sixty-years-later folk revivalists, but also a high degree of nauseating 21st-century pop 'kerching!' sensibility. Not a lot of soul in evidence.

Fantastic accompaniment to Inside Llewellyn David, one star knocked off because the DVD doesn't show "Please Mr Kennedy" even though it was recorded, shame. Brilliant if you want to broaden your musical horizons folk wise

I enjoyed "Inside Llewyn Davis", but it was an average Coen brother's film. I had moderate expectations for this documentary-style film and was pleasantly surprised. The performances are all excellent, and a nice blend of stage performances, backstage improvisation and jam sessions, and recording sessions in the studio. The Punch Brothers and The Avett Brothers were standouts for me, but all the artists put their own spin on the tune they tackled.

One thing in particular I liked was that the editing was thoughtful, with no fast cutting, allowing the camera to linger on a performer for 15 to 30 seconds or longer for most of the shots. Compared to the way most live music is edited lately it was a nice surprise.
