An early process piece, rigorously old-school. Music for 4 can be played by any multiple of four players, but each set of four should be from the same family of instruments (string quartet, four organs, etc.) in order to maintain a similarity of timbre among the four parts.
Here’s an excerpt from a live concert (the premiere performance) at Peabody Conservatory on July 12, 1985. Performers: Chia-Chi Lin & Thom Robinson (violins), Dave Marschall (viola), Peter Cejpek (cello), Kristie Born, Rob Haskins, Ray Sprenkle, and myself (electric pianos).
