The Harlem Cultural Festival和著名的伍德斯托克音乐节在同一个夏天举行,超过30万人参加,但如此盛大的音乐节却鲜有主流媒体报道。该纪录片回顾了当时的盛况The Harlem Cultural Festival took place the same summer as the famed Woodstock festival, and boasted an attendance on par with that concert 100 miles away. Over 300,000 people attended, yet it received virtually no coverage from the mainstream media. The 40 hours of never-seen-before footage has remained in storage for the past 50 years, keeping this incredible event in America's history lost - until now. It features many extraordinary performances by artists including Stevie Wonder, Sly and The Family Stone, Nina Simone, B.B. King, the Staple Singers, the 5th Dimension, David Ruffin, Mahalia Jackson, Ray Barretto and Gladys Knight and the Pips.
