Co-director of exhibitions and programmes at the Serpentine Gallery, a conversation with Hans Ulrich Obrist has infinite possibilities. Rem Koolhaas once said that the omnipresent Swiss-born curator and irrepressible interrogator left his native country because he talked too fast for the Swiss. Obrist has interviewed an ever-expanding spectrum of the great and good, from architects to linguists, philosophers, scientists, filmmakers and musicians, compiling a kind of ongoing Smithsonian Institute for the state of aesthetic thought in the 21st century, while his curatorial eye has transformed the possibilities of the white-walled gallery. On the day Frieze Art Fair opens, Jefferson Hack spoke to Obrist about enthusiasm, taking risks and parallel realities.
