Having my degree in music, and having worked with soloists over the years, I have some familiarity with voices; and hers is nothing short of other-wordly, rarified, pure, not your typical operatic voice. Her ability to switch "gears" effortlessly and her amazing voice and breath control is truly incredible. I could listen to her sing for hours!
Oh, and her hair is wonderful, too. But that's off-topic.
