In 2013, the Serpentine Gallery in London presents Fischli & Weiss’ first public sculpture in the United Kingdom, Rock on Top of another Rock, installed in Hyde Park, near the Gallery. This work was undertaken in tandem with the duo’s monumental rock project in Valdresflya, Norway, which was unveiled in the fall of 2012. The latter project was part of a nationwide effort by the National Tourist Routes in Norway, for which internationally renowned artists and architects have been invited to create works that dialogue with the Norwegian landscape, for each of the 18 roads spanning the country. Published to accompany this dual venture, this catalogue features essays by Patrick Frey, John Kelsey and Pernille Albrethsen as well as historical texts selected by the artists.
