Check out Art Rosenbaum's book "Folk Visions & Voices: Traditional Music and Song In North Georgia" (U.of Georgia Press 1983). Two companion LPs were issued by Folkways (Folkways FE 31461 & 31462). He did the text, collecting as well as drawings and paintings. Margo Newmark Rosenbaum did the photos.

There's a good discography of traditional Georgia music in it, as well.

Good stuff. Worth seeking out.
