Kafkas dance kids

Edit: I found the original upload on Youtube. It took some doing. By the boy's shirt, Chechen and by the printing on the wall Gold Dance.

I removed the Tweet because I don't like that Twitter girl. She brags about posting only nice things and speaking respectfully to everyone. While her uploads of men doing dumb things are titled "Idiot" and the uploads of women doing even dumber disastrous things are all titled, "Are you okay?"

But I must admit she's loaded with very good videos. 

I just cannot get over this one. All these dancers are fierce. In other videos even more so. Chechen. I had no idea they are this militaristic. The amazingly martial dances have a way, sort of, showing which dancers are straight fighter types and which ones are more gay ballet.
