As soon as I read this looking outwards was about sound a project I was tangentially involved in immediately came to mind. Actually quite similar to our professors work with music by a professor at Princeton university Perry Cook. He had a totally electronic orchestra.
He did work with my dad, a stone sculptor on a project for an installation in Princeton. They made a lithopone, historically a large upright stone xylophone. The installation quark park was many pieces done in collaboration between local artists and Princeton University scientists.
They created a system that mixed sounds from a stone sculpture being hit with random sounds recorded from the process of making the sculpture toy create a large electronic and stone instrument. When I was a little kid working with my dad on this project I had no idea really what electronic music really meant but as soon as we were showed the trumpet accompanied by a full electronic bras section in class I was reminded of this project.
