A Brooklyn-based artist has placed a public art installation in the center of New York’s City Hall Park that can’t be ignored. Inside the park, opposing rows of speakers line a path that connects the area’s central foundation to the nearby municipal building. As visitors come within earshot, they’ll hear the collective breaths–or attempts at it–from a few dozen people of all ages, fitness levels, and neighborhoods. The goal is to create a “canopy of breathing”, and to raise awareness to the respiratory issues that come about through polluted air.
