This is one movie I would like to see. I have been intending to find a copy of the book and just have not got around to it. Daniel Woodrell who lives in the southeast corner of Missouri has written several novels set in the Ozarks. I did not recognize but four names among the musicians but two were from the general area where Woodrell lives and the other, Billy Ward, I have seen and introduced at a few fiddle contests in Mountain View, Arkansas over the years. Van Colbert is a distinctive banjo player and Marideth Sisco, I know through a mutual friend. I was told that she had an interest in the music of May Kennedy McCord who was a fixture in the early days of interest in Ozark folklore and the source for "Palace Grand" which was picked up by Joan Baez and others. Van Colbert usually performs at the festival held annually in West Plains, Missouri in June. Dirt Road Delight is Billy Ward's band. There will, at least, be some southeast Missouri flavor to the music in the film. That area is quite rich in the Ozark mountain music traditions.
