The creation of a piece of music like this falls into three stages: the first is the selection of sonic materials and a musical mode - a constellation of musical relationships. These are then patterned and explored by a system of algorithms which vary and permutate the initial elements I feed into them, resulting in a constantly morphing stream (or river) of music. The third stage is listening. Once I have the system up and running I spend a long time - many days and weeks in fact - seeing what it does and fine-tuning the materials and sets of rules that run the algorithms. It’s a lot like gardening: you plant the seeds and then you keep tending to them until you get a garden you like."
