Leonard Bernstein's fame as a conductor and general cultural phenomenon has overshadowed his genius as a composer, despite the fact that some of his orchestral music has entered the standard repertoire and achieved a well deserved measure of popularity.  It includes three symphonies, several noteworthy pieces for soloists and orchestra, ballets that are often performed in concert, suites from his various stage works, music for voices and orchestra, and a substantial number of overtures and shorter pieces.  This book, in tandem with the accompanying CD, describes all of his significant concert music in a detailed but approachable way for listeners who want to explore his richly varied and colorful orchestral output in greater depth.
