Fretless, it'll run about the middle of the show; here's a description of the story from their website: Friday, March 23 ATCTalking Blues -- Talking Blues is a song form that can trace its' surface roots to a recording by the Greenville Trio in April of 1926. It's lineage goes much deeper - to spirituals - and an odd combination of the religious and the profane. The talking blues have served as a vehicle for social commentary for Woodie Guthrie, Bob Dylan, and hundreds of others. Musician and researcher Stephen Wade - creator of the stage show, "Banjo Dancing," and a contributor to numerous folklore journals - traces the history of the talking blues. (6:00)
