"Soundtrack to a Coup d'Etat" ... centers on the January 1961 assassination of Patrice Lumumba, less than a year after he was elected leader of the newly formed Democratic Republic of the Congo, at last independent from Belgium's colonial rule. America's CIA spearheaded the assassination plot, but this Cold War drama revolves like a kaleidoscope through a far-flung cast of characters, all of them intersecting at a pivotal moment in the 1960s. Soviet leader Nikita Khrushchev famously banged his shoe at the United Nations, which had welcomed 16 new African states to its ranks. Meanwhile, a host of American jazz greats were serving as cultural ambassadors Louis Armstrong, Duke Ellington and Dizzy Gillespie among them " ostensibly to promote Yankee goodwill and democratic values. Instead, they acted as unknowing decoys for CIA operations. Belgium's history is so tied to the Congo. All of Brussels is built with rubber money. Music and politics collide head-on near the end of the film, when [musician Abbey] Lincoln helps lead a group of 60 protesters " including Roach, Maya Angelou and Paul Robeson " as they loudly disrupt a meeting of the U.N. Security Council in the wake of Lumumba's assassination. "It's as James Baldwin says," [Belgian filmmaker Johan] Grimonprez suggests, offering a paraphrase of the author. "History is not the past. History is what we are made of. It's the present. It's what seeps into our skin and into our body and our bones."
