It’s Earth Month! In conjunction with the Portrait Gallery’s “Forces of Nature: Voices that Shaped Environmentalism” exhibition, Moveius Contemporary Ballet will present “Glacier: A Climate Change Ballet.” Moveius works at the intersection of policy and performance, creating a path for ballet to speak to contemporary issues and stories. In 2018, the company’s “Glacier” became the first ballet to be presented at an international climate conference. Created by Moveius Artistic Director Diana Movius, a climate policy expert, this piece imagines the dancers as melting polar ice caps; they ripple, crack and plunge in dance movements that connect the audience to the motion of ice in the arctic.
