On the occasion of its 40th anniversary, Taiwan’s Cloud Gate Dance Theatre takes grain, field, and flower as verdant muse in this celebration of the life cycle and natural beauty of the island’s essential crop. Dramatically poised against stunning video vistas of the Chihshang growing region, 24 dancers cross-pollinate modern dance and martial arts, ballet and qigong to become wind-rippled paddies, erotic agents of springtime germination, and fire walkers returning scorched seed to soil. Wielding bamboo sticks, recast as field implement, slender stalk, and weapon, they prod the seasons and coax valley rains as Taiwanese folk songs and Bellini arias waft in the wind.
