"Directions in the musical avant-garde in the past fifty years seem as numerous and diverse as the composers and their works. Yet these directions have historical motives and aesthetic values, traceable and uniquely observable due to their singularly radical nature. Building on the success of previous editions, the Seventh Edition of 'New Directions in Music' explores the history, philosophy, composers, and works of the avant-garde since the late 1940s, emphasizing works departing radically from tradition. Musicians and musical scholars of all levels will benefit from Cope's clear presentation, organizing a seemingly idiosyncratic field into a logical succession of ideas and developments."--Back cover.
