Sigmar Polke at the Tate Modern - to February 8th

'Sigmar Polke’s name isn’t (yet) up there with the giants of twentieth-century art. Maybe that’s because at every stage of his career he mocked, derided and rebelled against every art movement, historical legacy and consumerist ideal he encountered. Stuck in post-war Germany, between the Soviet realism of the East and the pop artistry of the West, Polke (1941-2010) fitted in nowhere.
If this major retrospective does its job, though, he’ll no longer be in the shadows of the likes of Warhol or his old pal Gerhard Richter.'   Time Out.
