Query: A Boheme for the ages.

This grand Zeffirelli production has a perfect cast. All singers look the parts and act well. Teresa Stratas was considered the greatest singing actress of her generation. Her fragile Mimi really hit the benchmark! Jose Carreras'passion and drop-dead handsomeness, coupled with a great voice and vocal technique provide the perfect Rodolpho. Renata Scotto's Musetta was brilliantly acted and sung by the greatest Italian diva of the day. All the other roles were well cast. The great Maestro and Music Director of the Metropolitan Opera,James Levine, presented an impassioned reading of the score-remarkably cognizant of the composer's wishes. The Met Opera orchestra is at it's best and the choruses are great!
