"I want my mind back," says Reginald D Hunter. And he would do: he's one of the few stand-up comedians who really uses it. This year, he's decrying the group mentality; the condition whereby he feels a kinship with other members of his own race, "even though I've never met most black people". It's an impulse that Edinburgh brings into focus for Hunter because, when he asks: "Are there any black people in the audience tonight?" he's answered by silence.
Hunter's reputation is for thoughtfulness and provocation. This year's show, A Mystery Wrapped Inside a Nigga, is ultimately less provocative than its title. But it's still forthright, intellectually curious - and funny. In his Deep South drawl, Hunter tells a story about a woman who curtailed sex with him at an advanced stage with the line: "I don't know you well enough." Which begs the question: where's the cut-off point? The tale illustrates Hunter's frustration with regurgitated opinions; he implores us to think for ourselves.
There are passages where his reflections aren't insightful enough to justify the low joke count. Having lambasted the television show, Trisha he later devotes five earnest minutes to confessing How I Cheated on My Girlfriend. Elsewhere, though, Hunter reaps a rich comedy yield from the tribal instinct and his own campaign for mental autonomy.
