Robots battle in a world that seems simultaneously prehistoric and futuristic in Rob Sato's watercolors. The artist (first featured in HF Vol. 16) defies the limitations of his medium both in content and in format. While watercolor paintings are typically kept small, he works at mural scale, rendering the precise outlines of his giant robots, warriors on horseback and bizarre humanoid characters. The softness of the watercolor is still there, adding a handmade touch to his mechanical subject matter. Sato's latest exhibition "Curses" opens on September 20 at Martha Otero Gallery in LA and features several massive works, folded paintings that become sculptural objects, some simplified sketches and painted baseballs that seem to take their cue from the cave walls of Lascaux.
