I was at the San Francisco Memorial Opera House at the time of this recording. And let me tell you the audience went wild for Sutherland and Pavorotti. This recording was done in 1975, with the two great singers at or near their miraculous prime. To hear a real Elvira, you must hear Sutherland, because she can deal with the coloratura as well as the vocal line. Wow! A coloratura soprano capable of singing Verdi! Pavorotti is spectacular in the difficult tenor role, matching the memory of Franco Corelli. I love this cd, a thrill a minute! If you love high notes, you will be very happy with this set.
