Once presumed lost, this newly restored, original cut of William Greaves’s rousing documentary about the 1972 National Black Political Convention is approximately 20 minutes longer than the version that aired on television (the longer iteration then considered too militant for broadcast). Greaves, a prolific documentarian best known for his 1968 avant-garde meta-documentary Symbiopsychotaxiplasm: Take One, was invited to chronicle the momentous occasion by co-organizer Amiri Baraka. Working with a small budget, Greaves assembled a three-camera skeleton crew, and the spirit of their filmmaking reflects the determined fervency of the subject matter. The Gary, Indiana-based convention, composed of delegates and spectators from a range of political backgrounds, was intended to espouse “unity without conformity,” per Baraka; unfortunately, the convention adjourned without a consensus being reached, causing some to consider it a failure. Greaves’s film largely proves otherwise, as the speakers and performers—who include Baraka, Jesse Jackson, Betty Shabazz, Bobby Seale, Issac Hayes, and Dick Gregory—pertinently elucidate the incommensurable experiences of Black Americans and stress the need for vast socio-political reform. (Furthermore, they later published the National Black Agenda on Malcolm X’s birthday.) The topics discussed are myriad, the sheer breadth of oppression and the problems which the delegates seek to solve immense. Greaves’s filmmaking is raw and inspired; the roving cameras capture the staggering magnitude of the task at hand, while frenetic editing and sudden, startling zooms intensify the sense of convivial disorder. Sidney Poitier and Harry Belafonte co-narrate; Belafonte reads poems written by Baraka and Langston Hughes, while Poitier reads Greaves’s duly magniloquent commentary.
