Good stuff. You should consider submitting this to 8DIO for their upcoming Free Angels library. If you submit 5 sounds, you get the library for free. I don't work for them or anything, I'm just a producer/engineer/musician who thought it sounded cool and that was the first thing that popped into my head. Either way, interesting thought and cool sound.
Really beautiful work!! At the moment, we are working on quite a contemporary version of William Shakespeare's The Tempest in Turku, Finland. And this I think will fit perfectly. I will somehow use it as a part of the brass section, really waiting to see how it works! Thanks!!
