I’ve watched the upcoming Hulu documentary about Sly Stone and the “Burden of Black Genius,” another dazzling Black Music History by Questlove, loved it and hope to get a review up in the next few days.

It premieres Feb. 13.

But I had forgotten this piece of history the film resurrects. Sly and his family band’s first appearance on “The Ed Sullivan Show” was something of a musically political earthquake.

Check this out.
