Mark Grotjahn's large new paintings abound with torrents of ropy impasto, laid down in thickets, cascading waves, and bundles that swell, braid around, or overlap one another.

'Summer of Love: Art of the Psychedelic Era,' the Whitney Museum's 40th-anniversary trip down counterculture memory lane, provides moments of buzzy fun, but it'll leave you only comfortably numb. For starters, it may be the whitest, straightest, most conservative show seen in a New York museum since psychedelia was new.

The New York gallery scene being as incredibly overpopulated and overmoneyed as it is, deep conflicts and contradictions aren't hard to find.

The giant white cube is now impeding rather than enhancing the rhythms of art. It preprograms a viewer's journey, shifts the emphasis from process to product, and lacks individuality and openness. It's not that art should be seen only in rutty bombed-out environments, but it should seem alive.

I see 30 to 40 gallery shows a week, and no matter what kind of mood I'm in, no matter how bad the art is, I almost always feel better afterward. I can learn as much from bad art as from good.

In the seventies, a group of American artists seized the means not of production but of reproduction. They tore apart visual culture at a time of no money, no market, and no one paying attention except other artists. Vietnam and Watergate had happened; everything in America was being questioned.

A sad fact of life lately at the Museum of Modern Art is that when it comes to group shows of contemporary painting from the collection, the bar has been set pretty low.
