Recordings of a recent multidisciplinary symposium on urbanization at Harvard GSD, including amongst others papers by Pier Vittorio Aureli, Colin McFarlane and Kees Christiaanse. There is an interesting exchange between Aureli and Neil Brenner at the end of panel 1, dealing with the history of the urban grid vis-à-vis capitalist development, and the political implications of diverse spatial configurations — lots to think about.
