This weekend of staged readings showcases an array of playwrights and features both emerging and established artists. Works to be read at the Winter Studio Festival include St. Petersburg: 1913 by Berkshire-based Robert Sugarman; Pulitzer Prize finalist The Clean House by Sarah Ruhl; the Obie Award-winning dark comedy Curse of the Starving Class by Sam Shepard; Beyond the Veil by Berkshire native Emily Devoti; and Anton Chekov’s classic The Cherry Orchard. Each reading is followed by a discussion.
