I stumbled across this and its companion episodes last night.
Soul! » November 1, 1972 | THIRTEEN
"Soul!" ran from 1968 to 1973 and was intended to be "not only a vehicle to promote African-American artistry, community and culture, but also a platform for political expression and the fight for social justice. It showcased classic live musical performances from funk, soul, jazz, and world musicians, and had in-depth, extraordinary interviews with political, sports, literary figures and more. It was the first program on WNET to be recorded with the then-new technology of videotape, and most of the shows were recorded in real-time—not live, but unedited."
In its six years "Soul!" aired a staggering number of amazing musicians, vocalists, and cultural icons - Mary Wells, Odetta, Dee Dee Warwick, B.B. King, The Delfonics, Pharoah Sanders, Amiri Baraka, James Baldwin, Betty Shabazz, Herbie Hancock, Nikki Giovanni, Max Roach, Stevie Wonder, and many more.
I haven't watched all of them yet, but I was digging this one (those outfits!) and the episode featuring Rahsaan Roland Kirk, in which he plays a nose flute as well as three saxophones at once (and it sounds good!). Check it out.
