Installations by Imi Knoebel, Charlotte Posenenske, and Franz Erhard Walther are now on view at Dia: Beacon. Idiosyncratic bodies of work of the three German artists are tied together through a shared sense of interactivity and interest in process. “These presentations offer an opportunity to experience the work of three artists whose practices represent a critical and transformative moment in art-making in Germany,” said the museum’s senior adjunct curator Donna De Salvo.
