Interference features the period of California artist David Simpson’s work from 1990 to 2012. The late 1980s signaled a transition away from the “hard-edged” abstract works which characterized Simpson’s early career. From contrasting bands of monochrome which hum with vibrant intensity, the artist turned to nebulous washes of interference paint. He has painted mostly monochromatic work that hovers in an almost alchemical realm. Using interference paints, composed of titanium dioxide electronically coated with mica particles, Simpson creates nuanced, mercurial paintings on smooth and active surfaces. The particles of mica act as tiny mirrors, reflecting light back and forth in ever more complicated patterns. The results transcend the very notion of paintings, as they play with the medium of light itself to create the monochromatic shift of color. Works in the Interference series interact with their surroundings, shifting in color and depth with changing light conditions. Through these pieces, Simpson seeks to “create space.” Indeed, Interference does not only create the illusion of limitless space; these paintings persuade viewers to explore their own environment, the refulgent canvases morphing with each subtle change in perspective. This collection of pieces draws its audience away from the frenzied modern world towards a radiant haze, offering a retreat into meditative static.
