The Sioux Falls Jazz and Blues fest gets bigger with the addition of Susan Tedeschi. DerekTrucks was already scheduled along with Robert Cray. Of course, to show how out of touch I am with contemporary blues artists, I didn't even know that Susan Tedeschi and Derek Trucks were married. Anyway it sound like a great show. It takes place July 20-21 in Yankton Trail Park, in Sioux Falls SD and is free to the public.
