Black choirs, or perhaps just black people, all have to dance and move around. I'd seen a few such choirs as a kid growing up in the American South, and I don't think discipline is ever something they would have been known for.

Russians do seem to culturally appreciate "high-quality" arts, whatever you'd call that--meaning orchestra, ballet, opera, and the like. There's almost no respect for that in American culture. You ask someone about Beethoven, you're more likely to get told about the Disney movie.
