This is so so awesome. And frankly, astounding.
NPR interviewed Italian-born, Diego Stucco, who makes music from trees, sand, dry cleaners, and who knows what else. That description alone may not have piqued your interest, but if you listen to it, you'll be floored. Here's the link to listen to it at NPR's site (from minute 12:30 to 18).
The interview is interesting and there's a funny story behind his music background, but if you'd rather watch how he does it, here's a youtube link, where you'll also be able to listen to / watch his other instruments, like sand, etc.
Let me know what you think!
