Using watercolors on handmade washi paper—are complex, lyrical, and moody, conjuring vistas of the natural world and the principles that define the movement and transformation of materials. Vibrant hues are overlaid with shimmering metallics; extremes of light and dark are juxtaposed in close proximity, creating surprising moments of chiaroscuro; and vein-like arrangements of great delicacy are organized into overarching passages notable for their graphic power. Throughout, Gilliam emerges as a virtuoso conductor, able to coax his materials into arresting compositions without sacrificing their inherent mutability and force. These paintings on paper reveal his range and ambition and help cement his status as one of the greatest living proponents of the power of abstraction.
