*50 copies limited edition* For almost a decade, starting in 1980, I worked almost exclusively with walkman recorders and cheap cassette players. From the beginning, sound recordings were intuitively for me "worlds in themselves", always markedly different from the original "reality", always full of their own thrilling features. I developed my own, very simple -but very efficient- techniques for sound transformation using only cassettes. I couldn't afford the prototypical "experimental" tools of those times: reel-to-reel recorders, synthesizers, rhythm boxes and the like. With hindsight, this limitation turned out to be a great advantage and an important lesson, that has remained vividly present for me until today: the most essential tools are spiritual, not technical.
