Cloud-Chamber Bowl

I dream I'm tiptoeing around a large house with empty rooms when I hear the sound of Harry Partch playing the cloud-chamber bowl. Here's a set he built way back, and you can click on this picture for a sound clip. A modern exponent of the cloud-chamber bowl is Max de Wardener. Here's some detail about him, and a review of his most recent recording - it's new music, but it's a natural acoustic and a particularly ethereal slice of digital culture.
