"Summer of Soul" is a music documentary that chronicles the six weeks during the summer of 1969 when thousands of people attended the Harlem Cultural Festival to celebrate Black history, culture, music, and fashion. Featuring concert performances by Stevie Wonder, Nina Simone, Sly and the Family Stone, Gladys Knight & the Pips, Mahalia Jackson, B.B. King, The 5th Dimension, and more, much of the footage was largely forgotten . . . until now. A testament to the healing power of music and community, "Summer of Soul" premiered at the Sundance Film Festival, where it won both the Grand Jury Prize and Audience Award.
