"Two pieces for Marco Lucchi" (March, 2012). Marco is another composer on the Auraltone Music label, and an on-line friend. He's recently composed several sets of pieces where one acoustic track (like a short piano piece) provides the source material for the others, which process the source electronically in different ways. I've had my own go at the same idea here.
