An waterfall of sumptous floating tone......brava.

Where and when is this fantastic performance from please?

I prefer the lower key, in part because the voice, and singer, are more relaxed and the music flows effortlessly. I never liked the early Casta Diva in the higher key. The phrases in Casta Diva are very long, and Norma itself very long and taxing for the soprano......so I understand any decision to avoid being too leisurely.
