Here's the live recording of my piece for Sinfonia Newydd, called Thrown. I've written about it in a short blog for their website, read it here.
"Different sounds echo at different speeds, and often the sound changes as it echoes – so it might start off harsh then with each echo become softer. A thick texture builds up quite quickly if several echoing sounds are layered, especially if each echo has its own echo, and so on."
I also reference Pink Floyd, so it can't be all bad.
