July 28–29, 8 PM, Israel’s highly regarded Vertigo Dance Company brings its vision of sustainability to PS21’s 100-acre campus with “One. One & One,” choreographed by Noa Wertheim and set to an original score for strings and vocals by Avi Belleli. Performed by ten dancers on a soil-covered floor, “One. One & One” reflects individuals’ desire for wholeness and spiritual connection to the natural world. The number “one” suggests solitude but also unity, and the work expresses the human tension between the competing desires for independence and connection—“the individual and his or her tribe” (Financial Times).
