Tongue & Groove arrives this month with literary offerings from some of the city's standout playwrights, novelists, poets, and screenwriters. Acclaimed novelist Mark Sarvas (Harry, Revised), screenwriter and novelist David Darmstaedter (scribe of El Cantante and the upcoming novel Jesus Feet), poet and playwright Susan Hayden (The Advantages of a Steep Roof), and poet Corrie Greathouse all take the stage this evening to keep the grand spoken-word tradition alive. They are the "tongue" portion of the night, accompanied by the "groove," NYC-based singer/songwriter Christiane Szabo, who plays rootsy, plaintive ballads that sound straight from the heartland.
