The 1969 Harlem Cultural Festival brought over 300,000 people to Harlem's 20-acre Mount Morris Park from June 29 to August 24, 1969 against a backdrop of enormous political, cultural and social change in the United States. The summer concert series featured huge acts, including B.B. King, Stevie Wonder and Nina Simone. During the same summer as the legendary Woodstock music festival, the Harlem concert series featured major African American artists against a backdrop of massive social change.
