Inspired by the city grid, jail cell windows, high-rise buildings and other structures designed to regulate and control human activity, Peter Halley’s Neo-Geo abstraction has exceeded into own regulatory bounds in a dramatic, maze-like installation at Chelsea’s Greene Naftali Gallery. Up and down stairs, around blind bends and through an eye-popping assault of day-glo color, visitors find their way through an environment that feels as if we’d stepped into one of Halley’s paintings. Here, a painting composed of stacked forms has an altar-like presence at the top of a vividly green staircase. (On view through Dec 20th).
