Simon Rattle is getting some of the first criticism of his career. “At 50, Rattle becomes a senior statesman, an establishment figure. He risks entering the kind of self-protective custody that turned Karajan from a powerfully engaged maestro into a misery on Parnassus, watching the world drift away from his concept and his grasp. Rattle has detached himself from his country without fully mastering German language or culture. He is perilously adrift from the way others are starting to perceive him. He may not enjoy reading bad reviews, but unless he gets to grips with shifting perceptions he will wind up in the ivory tower he has always struggled to escape. At 50, and on top of the world, Simon Rattle still has all to prove.”
