Threads stretched to breaking point criss-cross the sky. A web is woven five metres above the ground. For her latest spectacle, choreographer Myriam Gourfink has recruited trapeze artist Clémence Coconnier to spin a stately, delicate dance in which every slightest movement carries significance. Her stage, so to speak, is a suspended spider's web made of kevlar, every bit as finely wrought as the performance that unfolds on its surface. Arachnophobes need not attend.
