Two of America’s hottest Bluegrass bands come to Musicfest. Combining soulful virtuosity with soaring three-part harmonies, The Lonely Heartstring Band, 2015 International Bluegrass Music Association “Momentum Award” winners, are “in a class by themselves” (Tony Trischka, banjo legend). With #1 Billboard Bluegrass Chart recordings and “Best Record of the Year” praise, Mipso, takes four-part harmony and Appalachian influences into new territory with their imaginative songwriting and rhythmically powerful sound.
