Too bad didn't mange to sign up in time for their lessons. I have figured out what it is about her dancing though, it's the fact that you can almost count the beat and rhythm with her movements. Given the fact that Tango's often a melodic dance, I might be wrong in the fact that Mandria is in particular, a track which is highly rhythmic and uncompromisingly so, thus requiring more rhythmic play. But even on mute, you can almost hear the melody and rhythm just be looking at the footwork. Amazing stuff.
