Tenor Rolando Villazón has made his Metropolitan Opera directing debut with Bellini's “La Sonnambula.”.

William Christie is as busy as ever in a season celebrating his 80th birthday, conducting, playing the harpsichord, administering his Les Arts Florissants orchestral and vocal ensemble and teaching at The Juilliard School as he sticks with Baroque repertoire on period instruments, staying away from more modern composers.

The Metropolitan Opera will double cast a portion of Verdi and Puccini revivals and shift some contemporary compositions away from Saturdays at the recommendation of a consultant trying to boost the company’s finances.
