Two by Four, for Two Pianos, Four Hands (1983)

Professional level. My last serialized composition, with a complex matrix of interrelationships governing the pitch and rhythm; the details of that are here.  The four movements are played without pause, totalling 12-13 minutes. Includes some inside-the-piano playing. The numbers 2 and 4 are worked into the structure in a variety of ways, with an actual 2x4 being used near the end to play a giant tone cluster. $10 for two copies; order here. Hand manuscripted, but nice:
