you'd have to admit that the music is still fundamentally too fast for any sort of dancing without strain.. just the amount of movement of the center of gravity is a little odd for a step based dance.
Not that house steps can't be converted to suite this tempo.. but I'd still think there's not much to do in terms of steps (with lots of center mass movement) for this sort of tempo. Maybe stationary upper body movements, or gradual center of mass movements that occur accross several beats. The vertical down ups (Y axis) don't matter as much as sudden movements in the XZ axis plane. (ground plane)
Coincidentally, there is a house step that is also based on the "through" leg, while swapping the anchor leg position while pivoting the body at the waist. It's done alternating left and right legs, and I think it may come from a variation of a capoeira move.
I do think, though, that the steps in the video can be elaborated to a more "full" set of moves with a more balanced upper/lower body momentum balance, more efficient use of upper body both in terms of momentum and showmanship, and also expanding the style to include stationary (in place steps), mid position (ex: knees half bend), low position (down on knees), forward / back movement, left/right movement, turns of 90, 180, and 360. The upper/lower body balance is very important.
For example, typically, if the bottom (legs) are moving back and forth as much as this, the movements are countered by exaggerated arm movements, to balance the physical momentum, and also to balance the visual momentum. Just a plethora of different ways of converting the essence of the moves on the video into a fully developed dance style. It might be fun to spend some time developing it, as there isn't really an established style for hardcore / trance. (any 4x4 that's in the 140 neighborhood)
blah, anyway, just the "have directed choreographers and dancers" me just speaking.
Bottom line, it looks like lots of fun, and if I come accross a hardcore club, I'd be doing this step.
Hm, I'm curious when I'll see the first fitness studio ads for jumpen-workout...imagine a group of retired accountants doing this
