That’s the title of a 2010 BBC program narrated by Rolando Villazon. I don’t know how long it will stay on Youtube, but here it is. It’s almost an hour long and leaves out a lot of great tenors; but it’s worth watching.

I have been following a young Latvian soprano who I predict will be the next superstar. She is Kristine Opalais. She recently made a great debut at the Met in La Rondine and a marvelious DVD of Rusalka. Her latest DVD will be Eugene Onegin. The end of this month she will sing Tosca at ROH. Next year will include Manon Lescaut at ROH with Jonas, Since we have the same taste, except for Der Meister, I am referring her to you. You may know all about her already. Best regards to a great opera maven. Conrad
