Green noise is supposedly the background noise of the world. Green noise is also used to describe the overloading information of how to be green or more environmentally friendly. My project groene ruis, dutch for green noise, is a performance for a small tree, a hair dryer, live electronics and a performer. The performance takes the story of the greek nymph Daphne, who changed into a tree to escape the love of Apollo, as a departure point. It questions the different relationships between humans and their environment and their impossibility not to change their environment by their behaviour. In this performance I use the sound of the tree and the hairdryer not only as direct musical material but also for triggering soundfiles and synthesis processes, programmed in Max-MSP. The piece is a combination of directly amplified sounds (tree and hairdryer), prerecorded soundfiles and live-processed electronic sounds, all triggered by the performer.  A choreography of hand- and arm-movements are the basic score for the performer, and with these movements the sounds are controlled
