Hi
Sound Art Radio in Dartington, UK are currently broadcasting ( I think until tomorrow) "Winter" a section from a generative/database sound installation I made with ninety 4-5 year old children in a West London school in the Summer of 2008.
All the performances, text and music are by the kids.
They played hocketted hand chimes, thumb pianos, single string fiddles, 'whirly tubes' and created short texts.
I subsequently manipulated these and they are called in as loops, in a sort of "controlled random" way into a continuously unfolding ever changing composition which runs as an exe file from a PC.

The broadcast can be heard here:
