I cannot shake the feeling that the Coens don't really like folk music very much. There's something OFF about every performer other than Llewyn, even the "Clancy Brothers."

Is this because they consider Llewyn "authentic," (that eternal bugaboo of the folk scene) while the others are considered bland poseurs?

It's February, 1961. Later that year, Albert Grossman's trio of Peter, Paul and Mary will make its sweet, harmonic debut, and Llewyn will doubtless gag...
