ICA’€™s exhibition Charline von Heyl concluded with a week-long series of events that attempted to shed new light on the artist’s working methods and contexts, delving deeper into questions of abstraction within the history of painting and contemporary art. Kaja Silverman, the Katherine Stein Sachs (CW’69) and Keith L. Sachs (W’67) Professor of Art History, was in conversation with the artist at ICA.
