Tragically, Ian Welsh (1944–2014) did not live to see this exhibition of his latest work. Diagnosed with terminal cancer on the eve of his 70th birthday, he struggled to finish the two large paintings in his last series of works, entitled ‘Gravity’s Rainbow’. He found it increasingly difficult to stand to paint, but he worked, sitting down instead, on a group of six small canvases that have a mysterious linear assurance worthy of the best of late de Kooning.
