I believe the term you’re looking for is “stank face”. I’ll sometimes do this when I’m listening to a song and a part is especially virtuosic or surprising. When you see a musician doing it it’s often either concentration or them hitting sort of a flow state where they’re really feeling what they’re playing.

I recently got stuck with a Tesla rental on a trip and discovered that while it doesn’t have handy stuff like Android Auto, it does have a customizable fart feature. I knew Musk was a jackass, but that (and now this) really drives it home.
