Two strikingly different semi-spherical paintings appear to join together to provocative effect at the center of ‘Noisetone,’ one of Pamela Jorden’s new abstractions at Klaus von Nichtssagend Gallery in Tribeca. Both created from washes of paint and featuring a curving arch at the top like a dip in a wave or a celestial sphere, the palettes of each half create divergent moods that suggest different light conditions and landscapes. Purple and pink washes of color on the left uplift an otherwise bleak scene and off-set an overpoweringly rich combination of blue, green, red and yellow to the right. (On view through Dec 10th).
