Well, that was just amazing.

That was cool. and Jingle Bells.

I have some pretty major issues with the politics behind the creation of "arranged folklore," but some of it is really beautiful to watch nonetheless. Thanks!

When it started with all of them doing something with invisible strings or threads, I thought "I NEED THEM TO UNTANGLE THE WIRES BEHIND MY DESK!" (and probably ALL of them).

Still, if you could see their feet, you'd be watching some cool moonwalking...

Yeah, the no feet thing was mesmerizing. And I wonder if it (dance/song) had something to do with weaving.

Deborah, you are correct. The name of the piece is "Pryalitsa" ("The Spinner"), and it's a well-known Russian round dance (khorovod).

This particular version is from this movie, in which it's preceded by a choral arrangement of Feodor Chaliapin's "Lutchinushka" (The Little Birch Splinter).

You can read a tiny bit about the khorovod and its links to weaving here (bottom of p. 68).

"Pryalitsa" is a popular song among amateur folklorists, much in the way, say, "Yankee Doodle" is here in the USA. For example, here's a bunch of little kids dancing to this song. Here are some teenage girls singing it.
