Johnm just posted a song by James Lowry from the Virginia Traditions in the "what is this musician doing?" thread. This reminded me that the Virginia Traditions series of CDs is now being offered by Smithsonian Folkways as custom CDs or downloads. These had become harder to find, so good news. There's some great music on the ones I've heard. More info here:
