At Milonga de los Consagrados a woman caught my attention. Her waist was so flexible that she could turn her lower body over 90 degree against 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 seemed totally separated. She first turned her lower body and stepped forward to one side of her partner, then, turned her hips 180 degree and stepped to the other side of her partner with the other leg while her upper body remained permanently connected to her partner. At the end of the ocho sequence she always turned her hips to the side first, crossing her free leg and keeping it stylishly bent, and then turned her hips back to face her partner and put the bending leg down. She did so with elegance and beauty. No matter how complex the movement seemed, she executed it with great ease and style. No matter how fast the music sounded, she remained calm and unhurried, giving herself time to complete the step, and still managed to finish the step on the beat. She is a master of tango with an extraordinary musicality.
