Founded more than 30 years ago "to preserve African-American artistic expression and to enlighten, entertain and enrich a diverse community," Midtown's Ensemble Theatre gets better each season. The stage fare is distinctly varied and indefectibly produced with the company's usual high polish and downtown sass. With musicals, comedies, dramas and every combination thereof, the talent on display is prodigious, the works are given definitive productions and all that's needed is your presence. You can reach Ensemble by our beloved Metro light rail — the stop's right across the street. How convenient is that for great, enlightened theater?
