Summer of 1969. Over the course of six weeks, just one hundred miles south of Woodstock, the legendary Harlem Cultural Festival celebrated African American music and culture, and promoted Black pride and unity. The footage was largely forgotten–until now. In his acclaimed debut as a filmmaker, the musician Ahmir “Questlove” Thompson presents a powerful and transporting documentary—part music film, part historical record created around this epic event which has been largely forgotten, unlike the "white" Woodstock which has been widely documented and mystified. The documentary shines a light on the importance of history to our spiritual well-being and stands as a testament to the healing power of music during times of unrest, both past and present. We discover concert performances by Stevie Wonder, Nina Simone, Sly & the Family Stone, Gladys Knight & the Pips, Mahalia Jackson, B.B. King, The 5th Dimension, and more. Audience Award Sundance & Grand Jury Prize at the Sundance Film Festival 2021 and shortlisted for the Oscars 2022.
