Paul Panhuysen, Het Apollohuis in Eindhoven, was invited by De IJsbreker in Amsterdam in 1997 to curate a program of mechanical orchestras. This book documents the orchestras created by the six artists Trimpin, Frédéric Le Junter, Ulrich Eller, Ad van Buuren, Pierre Bastien and Harald Kubiczak. The CD features original recordings of each of the six orchestras. The accompanying essays by Kitty Zijlmans and Leon van Noorden use the programmatic title of the project, ’Music Without Musicians,’ as a point of departure for examining the absence of musicians in the process of making music.
