Rocks Rock

This is extremely rough, but I thought I'd give a sneak peak of the music I'm composing for a Documentary about Arches National Park. They asked me to use rocks. So that's what you are hearing. Rocks, marimba, flute, and I got a penny whistle in there too. Sort of a rocks and wind theme. Oh, and a plastic water bottle hittin those low notes. Now that's recycling.
