It isn’t news that art jargon can obscure more than it illuminates. But in Christian Jankowski’s video ‘Discourse News,’ the spectacle of a popular New York news anchor delivering the artist’s wordy definition of art from her usual desk in the NY1 studio makes visual art verbosity seem particularly absurd while also reminding viewers of how over-simplified normal news programs can be. (Jankowski’s latest solo show runs through July 28th at Friedrich Petzel Gallery.)
