This installation of 122,000 gallons of water pumped across the Armory's 33,000-square-foot floor includes periodic performances by the renowned French classical pianist Hélène Grimaud, who performs a program of water-themed music by Debussy, Ravel and Liszt, among others, as the space slowly fills with water. The result creates a still, mirrorlike surface reflecting the Armory's arching ceiling.
