The birth of Johannesburg-based artist Serge Alain Nitegeka’s daughter was a stimulus to move away from a primarily black color palette and to introduce shreds of sky-blues, canary-yellows and berry-reds into his hard-edged geometric abstractions. In an immersive, site-specific installation at Marianne Boesky Gallery, Nitegeka plays with overlaying geometric forms on wood panels. Not content with the flatness of the picture plane, the artist strives for three-dimensionality. He achieves depth through expertly placed color and line configurations and by occasionally introducing additional wood panels. Other times he pivots the paintings off the wall entirely and finally culminates in a geometric obstacle course in the connecting hallway between the two galleries. Throughout, stark black arteries suggest strength, support and stability – a psychological anchor, perhaps, for the trauma of the artist’s forced migration from his native Burundi. At Marianne Boesky through February 24.
