Overview:Leonard Bernstein was the composer who, more than anyone else in the twentieth century, embodied the trend we now call ‘cross-over.’ A brilliant musician and conductor, he wrote in the ‘classical’ style, but also wrote some of the best known ‘popular’ music of the century, from On The Town to West Side Story. By his own mixing of European classical, pop and Latin styles, Bernstein may have prefigured the next important phase in the music of our own time – the fusion of Western and Asian styles.
