Airs Thursday, February 21 at 8:00 p.m. When the discussion of contemporary American acoustic music arises, several different genres come to mind. If the ingredients of the genre include well-crafted songs, vivid arrangements, instrumental virtuosity, splendid improvisation, complete vocal harmony, as well as a mandolin, a banjo, and a dobro, well, the window gets narrowed down. One group that embodies all of these traits is The Infamous Stringdusters. Listen to the talented young newgrass ensemble The Infamous Stringdusters on this episode of SMF Live, featuring selections culled from their two shows at the Savannah Music Festival in Charles H. Morris Center.
