And the Butterflies Begin To Sing

I picked up an interesting CD on eBay: Morton Subotnick’s and the butterflies begin to sing for string quartet, bass, MIDI keyboard, and computer. The computer’s part is to listen to the MIDI instruments and processes the notes through an algorithm that controls the mixing and amplification of the other instruments as well as algorithmically performing three sampled instruments. Subotnick’s stuff is always interesting but tends to be hard to find.
