"I adored this lady, and I respected her work ethic. She always wanted to improve her understanding of a piece. "Casta Diva", [for instance] — what interested me most was how she gave the runs and the cadenzas words. That always floored me. I always felt I heard her saying something — it was never just singing notes. That alone is an art. It’s an art that you can try to achieve, but you can’t copy, because that’s just imitating without delving into [how she felt] about that particular fioritura. ... how many other artists since Callas have you heard and thought, "She sang gorgeously, but I never cried?""
