Inside a pitted, blackened, almost colonial frame, an allegory of sport, culture and art plays out on the square ground of a block wall carving. Like a rugby team, fifteen full blocks command the field, with half blocks as benched reserves. Each block has a defined position yet carries the same weight. Collectively impenetrable, the substrate quietly reflects the environment – absorbing warmth during the day and emitting heat at night. Crossing sport and culture, a 'first fifteen' also dominates the field of black painting, a contested abstract art form which aimed to promote collective ideals – from Malevich, Rauschenberg, Stella and Reinhardt in USA and Europe, to Mrkusich and Hotere closer to home. The geometric grid of multiple units in All Black sets the foundations for replication while the heat transfer properties of the concrete painting emulate bodily functions like a post-performance sweat.
