My work with sound started in the late '60's when I saw a film of the work of a man called Hans Jenny, a Swiss engineer and doctor who was influenced by the work of Rudolph Steiner. He was showing the effect of sound on matter. I saw that heaps of a matter which had no form, as soon as sound was introduced, took on the precise and exquisite patterns you find in nature and that the more the sound was sustained the more differentiated these patterns became.
