Instigated by what the Hong Kong Urban Renewal Authority (URA) terms "freezing surveys"—aimed at fixing legal claims to spaces (and thereby people) to frame cities as stable grids—"unfreezing" becomes a way to re-think and re-familiarise the relationship to cities we inhabit and travel across.
Benjamin and Tang propose that we see cities through the very practices that constitute them—how a city is "practiced" bears witness to how it is lived. Art then becomes a way to bring critical reexamination and repositioning of the city by reworking the very methods, tools, and representations that may otherwise become fixed.
