This was absolutely fantastic. One of the best documentaries I've seen in ages. Certainly one of the best about music. I tried to find more info about the flick, but there's just one PBS interview with the filmmaker. So definitely clue into this if you dig on quirky, honest filmmakers like Les Blank or Ross McElwee. The work is warm and respectful and revealing. Everything a cultural doc should be. Sometimes it seems to come dangerously close to mocking its subjects but then a humanist beat equalizes everything and film skirts back into a position of measured observation. As far as I'm concerned this is up there with "Sweet Grass", "Grey Gardens", "Gimme Shelter", "Sherman's March" and "Harland County, USA". It's just that good.
