This week, hosts Nick and Helen Forster welcome two world-class Americana groups to eTown. Guitar-plucking troubadour Pokey LaFarge and his band, the South City Three share the sounds of America’s past in a way that makes it almost impossible to believe these guys are still in their 20s. Shovels & Rope, a Charleston, South Carolina-based husband and wife duo, also bring a one-of-a-kind sound made with old guitars, harmonicas, soulful singing and a junkyard drum kit. Plus, our in-person eChievement Award interview is an environmental activist and co-founder of Earth Day.
