7 Must-See Gallery Shows in New York

Williams presents a series of distinct sculptures that seem somehow keyed into each other, like a ramshackle Rube Goldberg machine threading through the space. Natural materials appear synthetic, and vice versa, as with a mass of extruded thermal plastic that resembles a skull or shell, and hunks of “central Texas fossil” that might have been hewn by the artist, rather than the passing of time. One work, imposing as a highway barricade and titled “Black Hole,” is described as a “fiberglass and resin physics chalkboard sanded down to reveal its cast surface and steel support.”
