At Milonga de los Consagrados there was a woman who caught my attention. Her waist is so flexible that she can twist her lower body over 90 degree from her upper body. In such twisted poise she can step in any direction while her upper body is connected to her partner's torso.
When doing the front ocho, her upper body and lower body seem separated. She first turns her lower body and steps forward to one side of her partner, then, turns her hips 180 degree and steps to the other side of her partner with the other leg. While doing so her upper body remains constantly connected to her partner's torso. At the end of the sequence, she always turns her hips to one side first, crossing her free leg and keeping it stylishly bent before turning her hips back to face her partner and putting the bending leg down. She does so with elegance and beauty. No matter how complex the movement seems, she executes it with great ease and style. No matter how fast the music sounds, she remains calm and unhurried, giving herself time to complete the step, and still manages to finish the step on the beat. She is a master of tango with an extraordinary musicality.
