Anna Moffo and Stokowski have a very nice album.
I first heard Kiri and Jose late 80’s when I picked up a record from the British Council library of West Side Story. Kiri, Jose Carreras, and Marilyn Horne.
And introduction to Moffo was around the same time with the Rachmaninov vocalise on a home recorded cassette. I confess, hearing her for the first time was a tearful moment. She made one of the most beautiful melodies ever written even more beautiful. You can hear it in her recording.
Kiri though categorised as soprano had her singing voice sitting a bit lower and she would straddle the soprano and the mezzo ranges so well.
