Ideally, a biennial is an opportunity to redraw the global map with the center newly located. As new areas log on to the global contemporary circuit, a biennial can magnetize a location, drawing in attention, ideas and works from faraway places and aligning them with the local reality. A biennial can also serve the parallel function of directing local attention (of both artists and public) outward, toward those places, trends and individuals with strongest relevance to the interests of the biennial epicenter.
