New York City choreographer Rebecca Kelly spends her summers in the Adirondacks of northern New York State. Many of the ballets she choreographs relate to the pristine environment and beauty that surrounds her upstate. “Air” is a ballet based on the crisp, clean air in the mountainous region. It is a collaboration between the choreographer and Martha Gallagher, the Adirondack Harper. Paul Larson produced this piece for “Art Express” in 2005.
