Don’t worry! Those aren’t the banjos in Deliverance, just the strings of a down yonder band with an upright bass and mandolin. Forgive any yells or woooooo’s you may hear. The world can thank the great state of Kentucky for the genre’s invention and thank more Bill Monroe and the Blue Grass Boys for its name. If you’re a fan of relaxing on a lawn with a cold, local beer and have the sweet sounds of American medley grace your ears, then these festivals are a fit for you.
