Half-way through Soundtrack to a Coup D’Etat, John Coltrane and Duke Ellington’s soulful version of In a Sentimental Mood is interrupted. Suddenly, we see and hear Malcolm X giving a speech at New York’s Harlem Square in 1960. It’s like being shaken from a delicious reverie and thrown into the ice bath of reality.

“You’ll never get Mississippi straightened out,” Malcolm X snaps at the Harlem crowds, “until you start realising the connection with the Congo.” The curious connection between Black Americans’ fight for civil rights and the second-largest country in Africa is the subject of Johan Grimonprez’s documentary.

Early on, his film quotes political philosopher Frantz Fanon: “Africa is shaped like a gun, and the Congo is its trigger.” Described thus, the Congo doesn’t sound a peaceful place. “It isn’t,” says Grimonprez. “The Congo was long raped and plundered for its raw materials. It still is. You wouldn’t have your Teslas or your iPhones without raw material from the Congo.

“And I don’t mean rape just metaphorically. If you made a map of the east Congo showing where the mining is and the statistics of how many women are raped, it’s a one-on-one correlation.”
