National Educational Television broadcast as “The Sounds of Summer”. July 7th 1969 , Mississippi River Festival, Southern Illinois University, Edwardsville, Illinois. From the Alton Evening Telegraph, July 8, 1969.....“It is from widely separated backgrounds that Joni Mitchell and Arlo Guthrie, Monday night's entertainers at the Mississippi River Festival, derive their widely separated, but somehow similar musical styles. Joni, her powerful, bell-clear voice tracing faint images in melody, shows in her music and lyrics the philosophers' lament, a sophisticated sort of folk-blues. Joni's approach to the audience is through a high-and-mighty, and therefore mysteriously beautiful linkage of voice and song.”
