Kate Connolly profiles painter Imi Knoebel, whose work is on view at White Cube Bermondsey, London through September 13, 2015.

Connolly writes: "Knoebel’s Drachen Serie (kite series) is arguably the highlight of the White Cube show in London. Seven kites – light, bright aluminium shapes that hover high up on the eight-metre wall – take up one room. Nine other works – aluminium shapes and mirrors, in fluorescents and pastels – fill another. A piece called Ort-Rosa (rose place) resembles the open corner of a room, inviting you to step inside. And there are several hovering paintings, simply nam"ed Bild (picture), that look as if a Malevich had been made out of wax and left in the sun to melt."
