When the film West Side Story was released in 1961, New York's reviled Puerto Rican community gained some visibility and, over time, both in Spanish Harlem and the Bronx, neighborhoods plagued by poverty, drugs and crime, Hispanic identity was reborn and strengthened, thanks to a syncretic and intentionally popular music that eventually conquered the entire city.

During the same summer as Woodstock, over 300,000 people attended the Harlem Cultural Festival, celebrating African American music and culture, and promoting Black pride and unity. The footage from the festival sat in a basement, unseen for over 50 years, keeping this incredible event in America's history lost — until now.
