Flutterby™! : Dance as the art form of tyrrany

Help me out. I have this vague memory of an article from the early 2000s talking about how dance is the art form of authoritarian or tyrannical regimes. I'm pretty sure it wasn't Slate: Goose-stepping, the dance form of tyrants (as linked by Petronius back in 2003), although it was really similar to that, but talked more about ballet and other forms that have large groups of synchronized movement.

I've been thinking about this topic in the context of square dancing recently...
