If Chris Rock's Good Hair is an American arena concert, Akosua Adoma Owusu's Me Broni Ba (My White Baby) is a secret show: intimate, and the ideal realization of the vision of a valuable genius. Both are good, and in the world of commentary on the poetic, unfair world of black hair, both are good to have. In the world of art film, Owusu is the protégée of Kevin Jerome Everson, a filmmaker of international renown this former professor and student team exhibit together at "CUSP." They share a "sparse, rugged formalism," as Everson says of his work, as well as a lyrical attack on other people's observational deficiencies. Me Broni Ba ends with a double dose of sharp commentary: A woman twirls in slow motion, her long, long braids and her glowing necklaces fanning out around her as Sharon Jones does what only she can do to This Land Is Your Land.
