I enjoyed that and it is stunning but its not dancing. And I don't think they were actually performing to that track, some of the transitions don't fit the musical phrasing. I strongly suspect that was dubbed on afterwards, although an excellent piece of editing.
That on the other hand is dancing. They are interpreting the music and aside for a couple of the flashier tricks, there isn't much in there that couldn't have been choreographed sponteneously and lead.
I wish I knew how do they do ochos etc.,on a pavement without wrecking their ankles?
