There seem to be a lot of "music programming language" posts all of a sudden on HackerNews, many of which, like this one, have existed for years. Not that it's a problem, but I wonder why the sudden interest.
So here's the language (yet another) I used for the performance:
Glicol: Graph-oriented live coding language and audio DSP library written in Rust for making music in browsers

I've played with a lot of languages for music, including the ones you mention, and for my tastes, Scheme is the loveliest. Eventually I plan to play more with Extempore too.
Obviously, the live stream for last week is no longer live.
Is there a recording of it somewhere?
It was titled '"Compiling" Music' and some commentators took it not in the TeX way but in music being created programmatically.
