To enter Rita McBride’s Particulates at Dia: Chelsea one must go through a single industrial door posted with a caution for exposure to lasers and radiation. Once inside it takes a minute for your eyes to adjust to the darkness, green lasers beam from across the space and a dingy brick shelter the size of a basketball court comes into focus around you. Sixteen beams span the length of Dia: Chelsea, forming a hyperbola around a single axis. A slight buzzing rings in your ears and you notice a consistent mist dispersing over the beams, intensifying the green wherever the light intersects with moisture. An uneven fence, Guidance “Barriers”, restrains visitors from getting unlawfully close to the high-intensity lasers. The more time one spends in the space, the more Particulates becomes about the environment created around and because of the lasers than the lasers themselves. There is an uneasiness about being in this dark space with the perpetual buzzing and humidity from the mist. Yet there is a desire to move around the space, ignore the fence to go under the beams and experience the work like other installations or sculptures.
