NEW YORK (AP) — Marcello Giordani struggled mightily, his top notes effortful and thin. It turned out the tenor’s third performance of Aeneas in the Metropolitan Opera’s revival of Berlioz’s “Les Troyens” would be his last.

The Met announced Saturday that Giordani was withdrawing from the remaining four performances and was retiring the taxing role from his repertory. Bryan Hymel will take over, making his Met debut Wednesday night and singing the rest of the run, including a matinee on Jan. 5 that will be broadcast to theaters around the world.
