This is quite a piece you have here. I really enjoy the edginess it has, especially in the percussion, juxtaposed with the guttural bassoon and bass clarinet. For me, it certainly painted a very vivid picture, so I can see why you originally wanted to title it "Ephemeral Soundscape." Very atmospheric, but not in the, er...pan flute and harp sort of way. (Not that there's anything wrong with pan flutes and harps!)
Anyways, thanks for posting, you can thank MysteryComposer and his/her idea for the bump! Alas, I feel I've misremembered your style, and must continue searching. But who knows what other goodies I'll dig up?!
