Chicago playwright Joel Drake Johnson's tidy one-act isn't perfect, but it offers interesting perspective and burnishes its rough edges with some real literary style. And in the case of Black Theatre Troupe's production of Rasheeda Speaking, the cast and their director offset the script's soft spots with sturdy acting and an obvious affection for the material. In the lead, Lillie Richardson gave an almost maniacally jovial performance as a smart-tongued schemer. Her big speech toward the end of the play, in which she talks about riding the bus with white-collar white men, was an acting class in stage subtlety. Katie McFadzen made a convincing leap from confident to cowed, and both performances were polished by direction from Matthew Wiener.
