At a very early stage I realised that it's a real problem to perform electronic music on stage because electronic instruments are not particularly convincing on a visual point of view: somebody behind his computer, it's not particularly visual. So I was inspired by the opera. And what was the opera in the 19th century? It was the idea for a musician to join and to work, to collaborate with a stage director, with carpenters, painters, people doing decors, graphic artists to have a visual prolongation, a visual correspondence to their work. That's what I tried to do with the tools of my generation: electronics and video and lights and all that.
