Editors' Note We found the curatorial preface of Urban Nature at the Denver Botanic Gardens a bit coy - and that was because everyone we knew who had seen the show (or knew of it) had called it the "graffiti show" - so we were surprised to see the artists referred to in the preface as "street artists" and "muralists" with hardly a mention of graffiti anywhere, even though most of them admitted to having dabbled in that dark art at least once or twice: and spray paint laid heavy in the atmospherics. That was a bit of a problem. All the images - including the 36-foot one of two reclining ladies - were on standard panels of ecologically-approved material which made them seem a little like pictures painted for hanging on a wall except that someone had left them outside for everyone to see here around the garden. Ironically, these not particularly 'plein air' paintings are hung outside in 'plein air,' giving a new twist to that particular technique. More to the point: real graffiti uses what's at hand - walls with holes in them, or angles or unevenness of texture and composition or twelve feet high, walls of irregular shapes and sizes and much else. - e think the fact that each graffiti site poses a different challenge to the paint sprayer eliciting a unique dynamic and creativity - a kind of in your face attitude that does not stray so easily indoors or onto a pedestal. And this is not to diminish indoor art, just to say that ample sunlight and a certain surreptitiousness creates its own niche. So while we applaud the Botanic Gardens for trying to bring art into the garden, we wondered what other point this exhibit might have other than that you can erect paintings, much as you can, billboards, just about anywhere. - The Editors.
