This week: our final rebroadcast of the summer - next week we return to live broadcasts full-time with our annual Street Dance and Meatloaf Supper - originally from May 2014 at the Ryman Auditorium in Nashville, Tennessee. Brad Paisley sings an ode to the substrata and tectonic plates of the Cumberland Plateau (and his tune "Southern Comfort Zone"), Sturgill Simpson and his band perform "Turtles All the Way Down," and Sam Bush and Stuart Duncan team up on "My Little Girl in Tennessee." Plus, our friend Brian Dan Christensen joins us for a few Elvis tunes; Guy Noir checks out up-and-coming country singers at the Bluebird Cafe; and in Lake Wobegon, fishermen return to their pursuit of the famous walleye Old Pete.
