Artists Ben Rubin and Brian House’s “Terminal Moraine” opens at Brooklyn Botanical Gardens. Taking a meta-historical approach, its lone eponymous work models the local impact of the Laurentide ice sheet. Approximately 18,000 years ago, the 600 metre wall of ice flowed down the Hudson Valley and shaped the landscape—Rubin and House simulate the glacial retreat and forest growth that followed. In their sonification “cells expand and branch while crystalline structures gradually break apart,” helping listeners contemplate the deep time of history.
