Don, I watched a tv broadcast of Cecilia Bartoli in the role of Despina, and I think she stole the whole show. After that broadcast she was on radio in the role of Juliet, and her Juliet's Waltz was delightful. She's greatly versatile and unique, which is what makes a top performer in any field, really. The same, as you say, with Marilyn Horne. I think that is one thing that is so exciting about singing. Every voice is unique, not like something taken off the shelf. It's also the reason people need to nurture their own voice and not imitate someone else, let their own unique qualities come out.
