On April 6 Pirelli HangarBicocca will open Doubt, Carsten Höller’s solo exhibition. His work summons upon different states of mind: joy, illusion, and of course, “doubt”, which opens the door to new ways of perceiving reality. The exhibition, curated by Vicente Todolí, includes more than twenty large-scale works, both existent and new, aligned alongthe middle axis of the space. This alignment of works forms a central dividing wall, where visitors will see/experience only half of a given work, and have to remember the half they have seen until they encounter the other half on the other side. Large-scale installations, videos and photographs play with the spatial and temporal coordinates of the exhibition venue, charting a course between symmetry, duplication and reversal.
