Blue Ridge Music Trails
Although the National Country Music Contest in Warrenton, Virginia, is no more, there are dozens of similar music festivals throughout the southern Blue Ridge Mountains. For an excellent guide to these festivals and contests go to http://www.blueridgemusic.org/.
The site is described as "A Traveler's Guide to the Live Traditional Music and Dance Along the Blue Ridge."
There is also a book Blue Ridge Music Trails: Finding a Place in the Circle, by Fred Fussell, 2003, published by Univerisity of North Carolina Press.
