Director Hugo Jon Sayles’s choice to present Ain’t Misbehavin’ as a New York City “rent party” lent the collection of Depression-era tunes a laid-back informality that made audiences feel at home from the first note. The Broadway musical revue paid homage to the works of legendary blues man Fats Waller, the son of a high-profile minister who denounced jazz as a product of “the Devil’s workshop.” Thankfully, the top-notch cast, backed by a sparkling three-piece band, expertly blended the sublime with the risqué. And while their individual abilities impressed, the singers displayed even greater virtuosity during group numbers that ranged from riotous to soul-stirring.
