Appropriation is the idea that ate the art world. Go to any Chelsea gallery or international biennial and you'll find it. It's there in paintings of photographs, photographs of advertising, sculpture with ready-made objects, videos using already-existing film.

I'm noticing a new approach to art making in recent museum and gallery shows. It flickered into focus at the New Museum's 'Younger Than Jesus' last year and ran through the Whitney Biennial, and I'm seeing it blossom and bear fruit at 'Greater New York,' MoMA P.S. 1's twice-a-decade extravaganza of emerging local talent.

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.

'The Panorama' is also the last place anywhere in New York where the World Trade Center still stands, whole, as it stood in the early morning of September 11. I can also see the corner where I saw the first tower fall and howled out loud. Seeing the buildings again here is uplifting, healing.

Recessions are hard on people, but they are not hard on Art.

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.
