Teatro Dallas is in the midst of its 14th International Theater Festival with Teatro Abrego’s El Corazon de Antigona — Pati Domenech’s version of Antigone, Sophocles’ great drama about the daughter of Oedipus defying Creon, the new ruler of Thebes. Although Teatro Abrego is from Cantabria, Spain, English librettos are available. El Corazon runs this Saturday and Sunday at the Latino Cultural Center, and you can get tickets here.
