 With a palette that favors burnt umber, gray and army green, his dark thinly painted canvases and sculptures often come in a careworn palette of ash white, granite grey and lots of black.The paintings' stretchers sometimes extend into legs that might allow them to be carried like banners; some are paired with separately framed photo-based images of bearded 19th-century father figures or skeletons that seem to comment on the paintings.In his 2008 show "White Dada" at London's Alison Jacques Gallery, Dada-style montages and defaced pictures included a textbook description of electroconvulsive therapy and images of drugs of the medical, non-recreational kind.
