In 1969, during the same summer as Woodstock, a different music festival took place 100 miles away. More than 300,000 people attended the summer concert series known as the Harlem Cultural Festival. It was filmed, but after that summer, the footage sat in a basement for 50 years. It has never been seen - until now. Summer Of Soul is a stunning unearthed treasure destined to become a pillar of American music and African American history. In his striking debut as a filmmaker, the legendary musician Ahmir “Questlove” Thompson presents this transporting documentary—part concert film, part historical record—about an epic event that radiated the wholesale reevaluation of Black history, culture, fashion and music. This rich tapestry deftly incorporates interviews with historic personalities like Harlem “Ambassador” Musa Jackson, with an unforgettable musical revue that includes interviews and performances by varied artists like B.B. King, Cal Tjader, The Harlem Calypso Band, Hugh Masekela, Mongo Santamaria, Nina Simone, Sly & the Family Stone among many others, as well as many rare gems, such as a Stevie Wonder drum solo and a duet between Mahalia Jackson and Mavis Staples. Summer Of Soul shines a light on the importance of history to our spiritual well-being and stands as a testament to the healing power of music.
