When I went to the gallery what I saw didn't really interest me much, mainly because I don't really care for country music, but I did find the history of the people interesting. It was more of a study on hte people within the community and how they act rather than actual music. There were of course important figures from music, but it is about history and how everyone shapes it. I also found his talk to be interesting in the enthusiasm he put in his work.
It is always refreshing to hear someone be informal rather than pretentious of their work and I think I agree with him in that when you want to produce something he should stick to things he finds interesting because at least you'll enjoy it rather than putting yourself through misery.
