Last great exhibition you saw: Isa Genzken’s “Sesam öffne dich” (“Open sesame”). She’s a Cologne-based conceptual sculptress, and I like her work because it’s enigmatic, odd, and very arbitrary. Another was a retrospective of Louise Bourgeois called “A Stretch of Time.” The power and psychological deepness of her works impressed me a lot. Bourgeois is 97 years old and the best example of life as a neverending process of creativity.
