As long as folk music is folk music it isn't Art with a capital A. Art with a capital A is making millions out of displaying a shark in a tank of formaldehyde. Some people consider this to be a con trick.

Sitting with a group of musicians and playing and listening is a pleasure. I am not fussed whether or not anyone considers this to be art. It's certainly culture and I don't mind non players listening if they want to. They also contribute with attention, encouragement, applause and the occasional,(but not required) free drink.
