Currently the director of STEIM in Holland, Waisvisz was amongst the first to play with synthesizers on stage and very early developed and performed using gestural controllers. He also invented the notorious CrackleBox (feaured on 6 of the tracks on this CD). In 1978 he stopped recording. So this is a useful release that collects mostly informal recordings made between 1977 and 1995 and documents a legendary figure in the history of interactive electronics. A touch of Raymond Scott, lounge music, pop electronics, as well as more abstract, experimental pieces, this is a fascinating and listenable collection of formal and informal works.
