December 21–22, 7 pm in PS21's Black Box theater. "Phasmes" is a duet that explores the intimate encounter between human beings and the natural world. It is a companion piece to the earlier "Hêtre," a solo work that dramatizes a young woman’s retreat from the world into a mysterious, dreamlike forest. Displays of aerial and earthbound movement both delicate and poetic, acrobatic and muscular. A meeting of dance and circus arts, the works induce a slow metamorphosis of humans and organic matter, as performers confront nature, accompany it, dodge it, collide, and merge with it.
