The summer months turn IN THE AIR’s thoughts to meteorology, not to say beach weather, and so the title of the performance with which New York’s Gasser Grunert gallery will close Michael Alan’s current exhibition “Harmonious Opposites” caught our eye. “Cleaning the Clouds” is a six-hour “living installation” that takes place on July 29 from 6 p.m. to midnight, and is thoroughly participatory — the “clouds” are played by eight Alan collaborators who are in turn joined by audience members. It is described, in Gasser Grunert’s press release, in tones that toe the line between fairytale and hippie-dippie new-age spiritualism: the cloud cleaner is described as “pulling perfect clouds from the sky to clean them, honor them and attempt to change them” and yet “We fix what we can not, clouds are filled with love, [the cloud cleaner] must learn to let them be…. Come make art, live now!”  (IN THE AIR, having a soft spot for unusual clubs of all kinds, wonders if Alan has ever heard of the Cloud Appreciation Society, the Web site of which includes a section on “Music to Watch Clouds By,” but sadly no advice on cleaning them.)

Alan’s previous “living installations” have taken place at venues like artist Kenny Scharf’s Cosmic Cavern in Williamsburg, Brooklyn, which had performers slathered in Day-Glo hues. Show up, Alan’s Web site promises, and you might just “get turned into a sculpture.” Gilbert and George would surely approve.
