This is probably my family's favorite opera. We own the recording by Caballé and Domingo, and have listened to it many times. No one sings this role with more warmth and beauty than Caballé. We were excited to watch this opera, and we were able to borrow a copy through our inter-library loan system. It's true - Caballé is in top form here. She acts wonderfully and sings beautifully. But the acoustics of the theater made the other lead singers sound tinny and shrill. Vickers looked unconvincing and grouchy, and even missed one of the high notes. The worst part was the wind noise. It got so terrible that finally, we couldn't finish watching it. What an unfortunate thing to have made the one film of Caballé singing this beautiful opera, at an outdoor amphitheater! A terrible shame. I hope some new talent will come along and make a film of this opera with modern sound equipment - and not film it outdoors!
