What an exquisite instrument! She has fine things headed her way. But I’d ask her to dig deeper with her connection to “Casta Diva.” Liking Montserrat Caballé is not a good reason for singing an aria, much less claiming a profound connection with it. What specifically, in the text, resonates with her? Is she even aware of what she is singing about? She seems more concerned with other singers and her coloratura. This is approaching music from the outside in.
This reminds me of a Master Class I attended, taught by James Levine, who said, “When choosing a piece of music to sing, start with the text first. If you connect with the text, you’ll connect with the music and be able to make it your own.”
