John Mauceri offers a lively and passionate reassessment of classical music in the twentieth century, in which he argues that the history of music during the last century was shaped by its three major conflicts: World War I, World War II, and the Cold War. unlocks the mystery of why classical music seemingly produced so few eternal works after 1950, whereas other arts—popular music, Broadway, literature, painting, architecture, theater, cinema—have given the world myriad beloved and highly regarded masterpieces; why the composers considered the future of classical music in the 1920s disappeared from being performed after World War II; why the most heard symphonic scores of the century—music for Hollywood films—became the subject of brutal denigration and dismissal; why the avant-garde of the pre-World War I became the new lingua franca of the Cold War period in the West, and any music that veered from its requirements removed from being performed. Mauceri follows the data to demonstrate how the politics of global wars used an artform that many might consider unimportant—classical music—as a potent and effective symbol, target, and weapon. Based on more than a half-century of music making and discovery, is a plea to return the suppressed repertory—beautiful and unique expressions of humanity—to our concert halls and opera houses, much as the artwork stolen by the Nazis continues to be returned to its rightful owners.
