The Virginia-born John McCutcheon conveys a social activism in the great folk tradition, giving voice to the unheard and disenfranchised and telling tales of singular American character. The well-traveled troubadour, who once roamed the Appalachian region learning to play indigenous instruments, is a master of the genre’s arsenal, including guitar, banjo, autoharp, dulcimer, fiddle and Jew’s harp.
