The festival's 1969 program was an experiment in fusing jazz, soul, and rock music, and their respective audiences. The Thursday evening set featured performances by jazz musicians Sun Ra, Bill Evans, George Benson, Freddie Hubbard, and Anita O'Day, and a jazz jam session hosted by organist Jimmy Smith and featuring, among others, Art Blakey, Hampton Hawes, Sonny Stitt, and Howard McGhee. Friday afternoon featured a rock-oriented bill featuring the jazz-fusion group Blood, Sweat & Tears, eclectic jazz saxophonist Rahsaan Roland Kirk, and the rock acts The Jeff Beck Group, Ten Years After, and Jethro Tull. Saturday's schedule mixed jazz acts, such as Dave Brubeck and Miles Davis, with rock, blues and R&B artists such as John Mayall, Sly & The Family Stone, Frank Zappa and his band The Mothers of Invention, and O. C. Smith. Sunday's bill featured a morning performance of Brubeck's oratio "The Light in the Wilderness", an afternoon set by James Brown, and an evening finale headlined by the British rock band Led Zeppelin, jazz keyboardist Herbie Hancock, blues guitarists B.B King and Johnny Winter, and jazz drummer Buddy Rich and his orchestra.
