Darynn Zimmer, a soprano and former Sag Harbor resident who sang with the Choral Society of the Hamptons, will perform in two English-language operatic miniatures this weekend at the Poet’s Den and Gallery in East Harlem. Ms. Zimmer will play Mrs. Clancy in Lee Hoiby’s “The Italian Lesson,” based on the Ruth Draper monologue, and Estelle in Hugo Weisgall’s “The Stronger,” based on the Strindberg play. Neither work has been performed in New York City for more than 20 years.
