How fitting that Sadie Coles should choose an American painter to inaugurate her new gallery – it looks like a cross between a New York Chelsea loft and an LA warehouse. The industrial expanse is beautifully broken up by Sullivan’s spills and splashes of colour and metallic tones. His preoccupation with manipulating paint is revealed in these large spray paintings, whose surfaces swirl and crack to reveal layers within. Yet a repetitive canvas size and formulaic technique put the brakes on the bold possibilities of these apparently organic abstractions. This young artist seems rather too eager to fill the boots of his abstract-expressionist forefathers.
