He's really sort of the devil. He's completely emotionally detached. He has no empathy. You find that in psychopaths. It's about power with Voldemort. It's an aphrodisiac for him. Power makes him feel alive.

I try to deal with the complexities of power and social life, but as far as the visual presentation goes I purposely avoid a high degree of difficulty.

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.

Just as Pollock used the drip to meld process and product, Richter 'found' and used the smudge and the blur to ravish the eye, creating works of psychic and physical power.

Urs Fischer specializes in making jaws drop. Cutting giant holes in gallery walls, digging a crater in Gavin Brown's gallery floor in 2007, creating amazing hyperrealist wallpaper for a group show at Tony Shafrazi: It all percolates with uncanny destructiveness, operatic uncontrollability, and barbaric sculptural power.
