A few months ago Alain and I were talking about my bowl music project. Alain, a sound engineer with keen ears, was mastering the tracks, taking out some of the noise on my original recording (e.g. the sound of scraping a wooden dowel on bowl rim, room noise). He had noticed something.
“You know those little sparkly metallic sounds you thought were artifacts of my noise reduction?” he said to me. “They’re not artifacts. They’re built into the bowls themselves. They’re buried treasure.”
(Listen for sparkly metallic sounds at 2:20-2:30, among other places.)
