Producer-director Glenn Jordan brought together two Tennessee Williams plays, written twenty years apart, that examine the theme of isolation with searching clarity. The joint presentation, entitled “Dragon Country,” features the world premiere of “I Can’t Imagine Tomorrow,” starring Kim Stanley and William Redfield, and a much earlier work, “Talk to Me Like the Rain and Let Me Listen,” starring Lois Smith and Alan Mixon. Together, the dramas delve into “a land of endured but unendurable pain, where each one is so absorbed, deafened, blinded by his own journey across it, he sees, he looks for, no one else crawling across it with him.”
