For some reason, I am drawn to spontaneous music. As a kid, playing in a string quartet, we did this all the time..., but that predated everyone with a smart phone. I may have one or two Kodachrome snap shots of that history. Today, everyone has a movie camera in their smart phone. The multiplier-effect to share a moving example that occurred yesterday or last year in a distant location to move people on the other side of the globe is an incredible and powerful thing of Art and Beauty.
What is spontaneous music? Anything that comes together in a public place, even if staged - it's spontaneous unexpected art for the observer/listener.
