Sorry for being so slow--busy busy life! But look at this. Dmitry Morozov's Lesophon. It was wonderful to find it. We were given little radios and had to to tune them until we found the music...then walk towards the putative music location...which you will see in the imagery here.
Wonderful microtonal bending in the sound...
