The daxophone (I had the spelling wrong) can be played without a pickup,so I would call it acoustic. I just like things that make sound and don't care wther electricity is involved. I have found acoustic sound sources are often very harmonically rich,and it's nice to be able to play without electricity ,wires etc.But Processing acoustic sources is really my favorite thing to do lately. Just recording without processing blurs the distinctions,which I prefer not to recognize as boundaries I really like Cage's definition of music as Organized Sound.If ones organizational choices include random,or stochastic processes,it still fits. I'll check out the CD ,sounds interesting.
