The paintings in Philadelphia-based artist David Aipperspach’s current solo show at Tribeca’s Chart Gallery, ‘Prologue to a Garden Dark’ anticipate the slow end of a summer’s day by blending light and color from different times in a single scene. At the show’s entrance, a small painting tracks the path of the sun as it sinks though a grid of darkening colors, acting as a Rosetta stone for the same color shifts that appear in rectangles of stacked colors inset in the paintings. Acting as ‘clocks,’ the rectangles break into tranquil scenes, acting as abrupt reminders of the passage of time. (On view through April 30th in Tribeca).
