Alsop and Marx discuss performative architecture, design as street theatre and creating performance spaces as part of a public social ritual.
Alsop is the principal of London-based studio All Design, and has completed projects such as the Stirling Prize-winning Peckham Library in south east London and unveiled plans for an "unusual" skyscraper in Vauxhall, London. John Marx is the design principal of San Francisco based architecture firm Form 4 Architecture.
