in 1978 he began developing an idiosyncratic performance technique utilizing self-developed instruments formed from industrial materials such as stainless steel, titanium, and PVC plastics. critic John Buckley described his performances in this era: the instruments are collections of objects ... strung together with ropes and swung at varying speeds and directions to produce a fairly astonishing range of pitches and timbres. And the moves the guy goes through to manipulate these instruments are, for grace and athleticism, strong stuff. Z'EV is also interesting for the close correlation of visual and musical aspects, since the physical vibrations of the objects you see are the same as those picked up by the ears as sound. Also, since the rhythms of the work are dictated by the performer's every and any movement, an inevitable integrity unifies the act.
