 Interested in experimental and avant garde music he began creating custom-made instruments, also using synthesizers and tape recorders to manipulate recorded sounds.During this period he played guitar (used as a sound trigger device for synthesizer) in a free jazz group, Synthesis, and briefly, during 1974, with the electronic band Kraftwerk.Since 1975 he has worked from his own electronic music studio, latterly using personal computers entirely for composing and creating music.
