Watch the trailer for Questlove’s new documentary ‘Summer of Soul’

Questlove is gearing up for the release of his directorial debut with documentary Summer of Soul, and now a trailer for the anticipated film has been released.

With a full title of Summer of Soul (…Or, When the Revolution Could Not Be Televised), the documentary is about the Harlem Cultural Festival of 1969 – otherwise known as “the Black Woodstock” – which took place the same summer as Woodstock.

The trailer initially premiered during the 93rd Academy Awards, which Questlove served as music producer for.

Watch it below:

Footage from the 1969 festival sat in a basement for 50 years, with performances from the likes of Nina Simone, Stevie Wonder, B.B. King, Mahalia Jackson and more.

In a statement to IndieWire, Questlove – real name Ahmir Khalib Thompson – expressed his shock that footage of the event had gone unseen for so long.

“I personally live a life where musical gatherings and musical moments define my life,” he said.

“What would have happened if this was allowed a seat at the table? How much of a difference would that have made in my life? That was the moment that extinguished any doubt I had that I could do this.”

The film premiered at Sundance earlier this year, where it took home the Grand Jury Prize and the Audience Award in the U.S. documentary category.

Summer of Soul is set to hit American cinemas and streaming service Hulu in July.
