Yoshiaki Mochizuki’s Shifting Light

When the light shifts, Yoshiaki Mochizuki’s paintings come alive. Surfaces that seem like dull mirrors shift into prismatic events as light is corralled in the gouged layers of gesso and moon gold leaf. Exhibited at Marlborough’s Chelsea location, the paintings are untitled, but the show itself, “Summer Solstice,” takes its name from the sun’s passage over a languorous summer day, and the harsh-shadow trail it casts over beaches and sunbathers on rooftops and in city parks. These works, like sun-burnished skin, take time to reveal themselves, with the best, most robust color appearing only after the light has completed its course around the circumference of a body.
