Hello Milieu Quartet:
I am sorry that this is for percussion trio, not quartet. I'm working on a piece for percussion quartet now, but have nothing that I can submit to your call at the moment except for this (and I really wanted to submit to it).
If you were to select this work I would enthusiastically either add a fourth part, or replace the electronics with a fourth part. However, I understand if the submission is entirely ineligible.
