Dick Gregory’s audacious 1961 debut changed the face of African-American comedy. Live at Chicago’s Playboy Club, Gregory uproariously reflects on voting rights, foreign affairs and his chosen profession. “What do you demand out of a comic today?” he asks. “Good story, good plot, psychological reasoning, and above all, we must be funny. And you wonder why we’re sick, huh?” He ticks all those boxes and then some in this hilarious set.
