"The great explorer of complex rhythms and meters combined with a totally liberated spirit of dissonance, Edgar Varese dispensed with the term compositionin his works. He called his music “organized sound.” It is completely removed from the world of sounds observable in nature. Even in a score that bears the seemingly descriptive title Ameriques, Varese tends to represent the conceptual Americas as the birthplace of new science, new technology and new sound. His other works bear such scientific titles as Integrals and Hyperprism (a projection of a prism into higher dimensions). His unique score entitled Ionisation is arranged for pitchless percussion instruments and two sirens. The title refers to the disintegration of atomic nuclei."
