In this undated photo provided by the Houston Grand Opera, Melody Moore as Marta, left, and Michelle Breedt as Liese, perform during a dress rehearsal of the opera, "The Passenger," in Houston. "The Passenger" is the darkest of operas, a powerful and unrelentingly grim work that dares to grapple with the horrors of the Holocaust through a musical descent into Auschwitz.
