Stepping out of the elevator at Gagosian Gallery’s uptown, Madison Ave location, the roar of rushing water is immediate and surprisingly loud. Around the corner, squeezed into the main 6th floor exhibition space, is iconic conceptual artist Bruce Nauman’s sculpture of 97 cast bronze fish spouting water from their bodies as if they’d been hunted by rifle as well as hook and line. Elegant in photos, the mechanics of the piece – trailing tubes, a leaky basin, wires – dominate the in-person experience, creating typically Nauman-esque disconcertion. (‘One Hundred Fish Fountain’ is at Gagosian Gallery through Aug 31st).
