Michael presents a personal journey, choosing from those performances he considers 'classic.' Performers include Bill Monroe, Hazel Dickens and Alice Gerrard, Roger Sprung, The Country Gentlemen, The Lily Brothers, Eric Weisberg, Ralph Rinzler and Mike Seeger. Smithsonian Folkways: Sounds to Grow On is a 26-part series hosted by Michael Asch that features the original recordings of Folkways Records.
