It's the way-out daughter Donna of the premier family of country music, going for it in a freaked 60s bluegrass instrumental. Rock that mandolin Donna!
According to the bluegrasschamps website:
Donna Stoneman was born in Alexandria, Virginia. She is a master at playing the mandolin. Donna has resided in Nashville for many years. She is now a minister of the Gospel and has traveled to many foreign countries delivering her ministry. She enjoys interjecting the mandolin and her puppets in her performances at churches and Christian events.
