Not music but my city has a surprising handful of puppetry troops that put on absolutely phenomenal performances.

They use really elaborate hand built stages, puppets, and other contraption. projectors and paper cut outs for wild visual overlays, compelling emotionally engaging scenes and It’s always for crowds of ~30 or fewer people sitting on a floor. It really feels like the textbook definition of childlike wonder. They are by far the events I get most hype about when I see a flyer / post.
