A short documentary of the performance Cloud Chamber. From Scientific American: Not everyone appreciates the beauty of a simple cloud chamber, but Alexis Kirke is a fellow aficionado. He’s the composer in residence at the Plymouth Marine Institute in England, a research fellow at Plymouth University, and holds PhDs in both the arts and technology. So it’s not surprising that much of his multimedia work across multiple platforms has a scientific bent, including Cloud Chamber, a duet for violin and live subatomic particles. Yeah, you read that right: subatomic particles. The performance requires not just a human violinist, but a working cloud chamber with a camera mounted over it. The camera records the tracks left by cosmic rays and converts them into synthesized music.
