As another reviewer stated, they just TALK about the country music. You don't get to hear much at all except tiny sound bytes. I imagine this has to do with copyright and the producers of the documentary were not prepared to pay up on the royalties, which is understandable -- but it left a gaping hole in the video.
I have to give it a few stars for telling me things I never knew, not having been a fan of this music genre called country for most of the first 50-plus years of my life (excepting some crossovers like Willie Nelson and a little bit of this and this here and there). I was for instance surprised to learn that "flatlander" music was a subgenre and a sort of rebellion against "mountain" music. I also used to think that "bluegrass" and "country" to two different genres. I had heard it once before and was waiting for some confirmation that I got here, that the banjo came from Africa.
This video takes on a LOT of genres and subgenres of "country" music and shares a lot of interesting history, but in the end for me it was terribly disappointing not to hear a full song of each and every genre spoken about. Things of interest are fodder for the mind, but I imagine many people are like me in that they had hoped they would get to get an earful of the music itself rather than an earful of a broad spectrum of celebrity names. Some who are every bit as good or better at their craft than the U.S. celebrities don't seem to be much a part of this video at all. From what I understand there are a lot of country singers who are from the U.S. and are celebrities in Europe while being all but unknown in the States (such a Butch Hancock, whose first band was called The Flatlanders).
This is a video I would not care to watch more than once.
