[From Hannah McCann at the Culture desk] English architect, writer, and educator Peter Cook speaks tonight at SCI-Arc on the alluringly titled subject of "Hard and Soft"--presumably his work with Archigram in the 1960s, CRABstudio (Cook-Robotham Architecture Bureau) Architects now, and his design for integrating urban life with the campus of the Vienna University of Economics and Business, to be featured in the SCI-Arc exhibition "L.A. in Wien/Wien in L.A." opening July 24.
