In Contrappunto (the first of my Inventions for data stream) the data stream (from the AFLOWLIB.org entry for Silicon) is manipulated during the live performance creating a musical material that will be influenced by the performer in any instance of execution. This is where the CADDC environment is most versatile, allowing for a large degree of improvisation and for a broad palette of esthetic choices. The duration of the piece is open and the recording on SoundCloud is just an example of the infinite possibilities that this piece opens.
