This month we hear from the makers of the five films nominated for the Academy Award for best feature documentary. Today, Johan Grimonprez, director of "Soundtrack to a Coup D’Etat", discusses his film's "fusion of jazz and geopolitics" that touches on colonialism, racism, the 1961 assassination of Congolese independence leader Patrice Lumumba, and a State Department-backed goodwill tour by jazz musicians like Louis Armstrong and Nina Simone.
