YouTube is telling me I need to see Vesselina Kasarova. She is in Zurich next year, but I can't find her when I will be there. I am most familiar with her Mozart recording, and I felt she attacked the arias in a very aggressive way that I did not like. It would be especially nice to see her in La Favorite since she is not really a Verdi Mezzo. Her "O mio Fernando" on YouTube is just what I would want to hear.
Her website doesn't show her future schedule, but I see the Paris Opera has her listed for Alcina in November and once in December.
