 Along with Horn, Langan, Dudley and Paul Morley, Jeczalik co-founded Art of Noise in 1983.As a freelancer, he was in a minority of musicians around the globe that used CMIs to create music, but unlike his contemporaries, at the time Jeczalik developed his own way of creating noises by taking advantage of the machine's then-poor quality audio output and transformed the distorted samples into unrecognisable sounds.Some of these early ideas can be heard on the Kate Bush album "The Dreaming".
