I also take pleasure in the so-called negative power in Grotjahn's work. That is, I love his paintings for what they are not. Unlike much art of the past decade, Grotjahn isn't simply working from a prescribed checklist of academically acceptable, curator-approved 'isms' and twists.

After its hothouse incubation in the seventies, appropriation breathed important new life into art. This life flowered spectacularly over the decades - even if it's now close to aesthetic kudzu.

Although I adore the Italian High Renaissance, I'd rather look at Mannerism. The former is ordered, integrated, otherworldly, and grandiose; it leaves you feeling hungry for something flawed and of-the-flesh.

Artschwager's art always involves looking closely at surfaces, questions what an object is, wants to make you forget the name of the thing you're looking at so that it might mushroom in your mind into something that triggers unexpected infinities.
