As American cities exploded into violence following the murder of Martin Luther King, Jr. in April of 1968, tensions grew so heavy in Boston that a planned James Brown concert was nearly canceled. Instead, Brown took the stage and his performance that night was credited with playing a role in shielding the city from a tragic meltdown. This documentary tells the compelling tale of the event using archival concert footage and interviews. 175 min. Standard; Soundtrack: English; interviews.
