Warren O’Brien is a prolific painter whose abstract images reflect the rhythm and repetition of his process. The layering of rich, radiant colours affords the work depth and texture, while the free brush work and dripped paint brings to mind the spontaneous style of abstract expressionism. His use of the repeated arc motif based on the architectural form of the arched window is magnetic in effect, drawing attention to the many complex layers of the works. He builds upon his well-defined style of mark making by scrapings manic text and text-like marks into the paint.

O’Brien has been a regular artist at Arts Project Australia since 2005. He has been included in numerous group exhibitions including at Melbourne Art Fair and Linden New Art, Melbourne as well as Gallery 101, Ontario. His work is held in private collections throughout Australia.
