In Image of Absalon to be Projected Until it Vanishes, Matthew Buckingham projects a picture of Copenhagen’s once-controversial statue of archbishop Absalon. Over the course of the exhibition, the 35mm slide gradually fades from the heat of the projector lamp. Elsewhere in Time Again, a SculptureCenter exhibition curated by Fionn Meade, Laure Prouvost enjoins us to remember the stream of images in her video montage It, Heat, Hit. Repetition or restaging of the past recur in work ranging from video and installation to sculpture and painting. In a small show-within-the-show featuring artists returning to their past work, Josef Strau revisits an essay he wrote about Cologne artists’ “non-productive attitude.” This is not Proust’s “Time Regained,” Meade explains, but the less nostalgic iteration of “Time Again.”
