Barbara Kruger’s iconic 1987 ‘I shop therefore I am’ image takes on new and damning forms in her powerful solo show at David Zwirner Gallery in Chelsea, where she updates the piece as a single channel video. The graphic materializes as if composed of puzzle pieces which break apart and reassemble every 57 seconds with new, provocative texts, including, “I am therefore I hate” and “I sext therefore I am.” Surrounded by wallpaper featuring hands holding imagery and messaging culled from the Internet, Kruger questions the values evidenced in contemporary culture and on-line discourse. (On view in Chelsea through Aug 12th).
