Original Luciano Berio's off-camera commentary: "This is the RAI Studio of Fonologia in Milan, one of the first electronic music studio. There are sound generators, filters, tape recorders, modulators, mixers and also excellent technicians (Marino Zuccheri). Here you can find all you need to produce electronic music in a good mood. It's necessary when you have to go back and forth on the sound equipment, to do a hundred of manual hand-works and to patiently cut the magnetic tape with the scissors".
