This season, TRT brought us two of its three inaugural plays: Cold Storage and A Streetcar Named Desire. Ronald Ribman’s Cold Storage, the story of two hospital patients, offered a superb performance by TRT artistic director C. David Frankel, and Streetcar boasted a dazzling Blanche DuBois courtesy of the astonishing Emilia Sargent. When a one-year-old company can already offer these excellent portrayals, the prognosis is very good. Keep your eye on TRT.
