Andre Previn is better-known as a conductor than a composer. But he’s working on changing that. “Temperamentally, Previn is probably unique among American composers in that he has nothing to prove. Thanks to all those years on the Hollywood treadmill, he writes with speed and fluency. Whatever the reason, some of Previn’s music is wonderful, and some of it meanders. You could wonder to what extent Previn knows the difference – or if he takes his composing life seriously enough to revise more rigorously.”
