Everyone is invited to enjoy a free concert of bluegrass and Appalachian mountain music this Sunday, October 20, from 4 to 6 p.m. It will be held at the Swarthmore Borough Hall Amphitheater and will feature Noggin Hill, an authentic bluegrass, mountain, and country music band, incorporating musical elements of folk-jazz and the American songbook. The concert is a big “thank you” to the Swarthmore community for the assistance given to the Appalachia Service Project (ASP) this year, and the work done in Chavies, Kentucky, making homes there warmer, safer, and drier.
