This weekend, on the Allegheny River in Pittsburgh, “artist Michael Pestel performed improvisational tunes while seated at a baby grand piano, floating on a section of a dock going down the back channel of the [river]. The performance art, which lasted about an hour, was videotaped… for showing during an exhibition that will open Friday at Chatham College, where Pestel is an assocate professor.” The event was inspired by composer Heitor Villa-Lobos, who once wrote of dreaming such a scene. Was it particularly groundbreaking? A window to a new breed of performance and/or photographic art? No, not really. But you’ve gotta see this picture.
