A ground-breaking investigation of how new technological developments have influenced the creative possibilities of composers of computer music in the last 50 years. It is rare to find such well-curated analytical material on electroacoustic music. I have known Francis Dhomont's Phonurgie since its creation and talked with the composer about it many times. I analyzed, performed, and taught the work for the past 20 years, and yet, there was so much new information to discover here. This book will deepen my appreciation for these compositions and present an excellent resource for my students.
