History - they say - is written by the victors, and culture is created by those that have the biggest voice.
In 1969, around about the same time that Woodstock was taking place, another significant cultural event was happening in America that was attended by more than 300 000 people.
Until now however, there has been no record of it even happening.
'Summer of Soul' is a documentary film about the 1969 Harlem Culture Festival that featured acts like Nina Simone, B.B. King, Stevie Wonder and Hugh Masekela.
The 50-year old footage was found buried in a dark basement and restored.
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 during times of unrest, both past and present.
Creative expression is better informed when it is exposed to a diversity of perspectives. Narrow-mindedness has never produced any kind of creativity that benefits the whole of society - so if you are a fan of Woodstock, you'll love it even more after seeing this film too.
Looks like a few lost voices are finally being found and a richer cultural heritage is thankfully now available to all.
Summer of Soul premiered at the Sundance Film Festival, where it won both the Grand Jury Prize and Audience Award.
