Nr. 2 of Galactica Suite, recently revised, as the original was playable only by computer, not live performers. I had the idea of an orchestral suite that would use live performers, including a performer who would control the computer parts, but the software was not good, and has disappeared.
Spiral galaxies are not really such tranquil things as this piece might suggest, but photos of them are quite restful and pacifying (to me).
There now remains one more movement of the Galactica Suite, which is still a scattering of manuscript paper drifting around the room.
This link will display various options. Near the top, you can select streaming audio by whacking "Play MP3". I don't know how well this works, as streaming audio for me is hopeless.
If you have the Scorch plug in, you will also see the score, if you wish to look at it. If you don't have the plug-in, you will see a blank where the score should be, with instructions of how to get the plug in if you so desire.
Below all this, under "details" you can select Download MP3, which is useful if streaming audio is not good for you.
