Shadowproof obtained 28 pages of FBI records regarding Gil Scott-Heron under the Freedom of Information Act (FOIA). Born in Chicago in 1949, Scott-Heron was a renowned African-American poet and musician, perhaps most famous for his 1974 album, “The Revolution Will Not Be Televised.”

The declassified records include a memo to the FBI Director about a party thrown by the socialist All African People’s Revolutionary Party, at which Scott-Heron was scheduled to speak. The memo states that its contents concern an “extremist matter.”
