Comprised primarily of “lost” footage of the 1969 Harlem Cultural Festival, Summer Of Soul chronicles the forgotten concert with performances from Nina Simone, Stevie Wonder, Gladys Knight, Mahalia Jackson, and more. This Academy Award was the first for Thompson, who is also working on a James Brown documentary with Mick Jagger, and a documentary on Sly Stone. Questlove is also working with his Roots bandmate Black Thought on a Disney animated series.
