I hear this concert from London and also I hear mr. Florez live in Bucharest, Romania in Rossini's STABAT MATER (conducted by R.MUTI) in 28.09.2001 and I think mr. Florez is the best tenor of this young generation for Rossini & Bellini and also Mozart. I can say just a single word: BRAVISSSSSSSSIMO, Juan Diego Florez.
You are right about Florez: a wonderous voice. Let's hope his PR people do him justice, and that he has the luck needed to reach super-stardom. Unfortunately, his gifts and hard work aren't enough. His kind of artistry helps one forget momentarily the negative aspects of human nature, such as the events of 9/11, and some of us really need this singer.
