Juliana Cerqueira Leite’s show “UP DOWN IN OUT” at the Trolley Gallery in London is a welcome addition to the current crop of artists who are measuring the world using themselves as the yardstick. Whether it be Marlene Dumas spreading her arms to measure the length of her grave or Antti Laitinen digging tunnels or bucking watery currents with a made to measure island or Rebecca Warren tussling with material that is too heavy for her, artists are physically wrestling with the weight of earthly and human substance.
