It all begins with a hand. Two arms follow that speak of flying, head down. Marthe Krummenacher has taken off into Obtus, a solo that carries its name well for as much as the dancer begins a persistent exploration of a ray of light. Meditative gestures, slow, continuous movements, a body in peril which finds its most beautiful expressions when equilibrium is pushed to its limits. The ex-Forsythe dancer moves with exquisite precision and sensitivity, playing with a ramp of neon lights making parts or all of her body disappear.
