Sitting in a Room is a major solo exhibition by the American artist Rachel Harrison. Her nimble, layered method of artmaking has always escaped easy categorization, but persists in devising ways to reframe the viewer’s encounter with her surroundings. That alertness to conditions of display extends to her room-scaled approach to this exhibition, which the artist describes as neither a survey nor a retrospective, but rather an intuitive remapping of her latest work’s conceptual coordinates.
