Cannon, who was blind, was always there, ready to give and take ideas, enthusiasms, opinions. The Biennial has recreated, or reimagined, the apartment setting, bringing in old furniture, installing a wall painting by Cannon’s friend, the artist David Hammons, and including personal items, like Cannon’s ever-present ashtray, along with stacks of the books, notebooks and magazines that filled the place. In short, it conjures up the ghost of a utopian situation.
