The Harlem Cultural Festival, also known as "Black Woodstock", was a series of music concerts held in Harlem, Manhattan, New York City during the summer of 1969 to celebrate African American music and culture and to promote the continued politics of black pride. The concerts took place in Harlem's Mount Morris Park on Sundays at 3PM from June 29, 1969 to August 24, 1969. The manifestation came soon after the Watts Riots, and the assassinations of Malcolm X and Martin Luther King.
