Rolf Liebermann - Les Echanges



Rolf Liebermann composed this piece for the Swiss Expo (National exhibition) 1964. It was displayed as an installation in the pavillion for banking, trade, insurance, office-organisation etc. They wanted to "make the offices talk for themselves", as an "orchestra conducted by an electronic control unit". Liebermann worked for months with engineers. It included 16 typewriters, 18 calculator machines, 10 cash registers, 12 punching card machines, 8 telexes, 16 telephones, 1 fork lift and many other machines that were new at the time and are now obsolete.
It was also released on 7", including a "Jazzversion" on the b side, played by Daniel Humair (dr), Pierre Favre (dr) and George Gruntz (prepared piano).
The piece was also an important inspiration for the Swiss pioneer of electronic Jazz/Pop/Advertising music, Bruno Spoerri. He told me it was a motivation to seriously engage in electronic music.
