"Summer of Soul": Rescuing a historic Harlem music festival
A new documentary, featuring rarely-seen footage, captures the magic of a 1969 music festival held at Mount Morris Park in Harlem, attended by 300,000 people. The festival had long been forgotten in the shadow of that other New York music festival, Woodstock. Contributor Hua Hsu talks with "Summer of Soul" director Ahmir "Questlove" Thompson, bandleader of The Roots, about reviving the legacy of the Harlem Cultural Festival, which featured such stars as Sly and the Family Stone and Stevie Wonder.
