The Met embraces all kind of repertoires, for our greatest delight. This month, don't miss the irresistible Sonya Yoncheva starring as Mimi in Puccini's La Bohème: her tenderness is the very opposite of Nina Stemme's fiery Elektra, in a production conducted by no less than Esa-Pekka Salonen and staged by the late Patrice Chéreau.
