DE KRAAKDOZENTENTOONSTELLING VAN MICHEL WAISVISZ. 1975.

Amsterdam: Stedelijk Museum, 1975

20.7 x 13.8cm, 12pp plus foldout plan and original typographic wrappers. Exhibition catalogue which presented the history and use of the “kraakdoos” or “cracklebox” an early form of synthesiser which generate various unusual sounds and tones when contacts on the top of the box were pressed by the performer. The electronic circuit actually passes through the player’s body and his or her movements alter the sound. There are 4 b/w images of the box and performers.

Wiki notes: “The concept was first conceived by Michel Waisvisz and Geert Hamelberg in the 1960s, and developed further in the 1970s when Waisvisz joined the STEIM foundation in Amsterdam, Netherlands. The kraakdoos is a simple device, based on a single operational amplifier (one of the earliest models to be produced) and a few transistors, and can be constructed with only a basic understanding of electronics.”

This is in VG+ condition and an interesting document of early electronic art.
