In the fall of 2014 the internationally acclaimed Danish-Icelandic artist Olafur Eliasson (born 1967) showed the major solo exhibition Riverbed at Louisiana Museum of Modern Art in Denmark. The exhibition included a monumental site-specific intervention--a huge landscape of rocks and streaming water--occupying the main part of Louisiana's exhibition space in what was his first solo show in the renowned museum, located on the outskirts of Copenhagen. The installation radically transforms the museum and the visitors' journey through this reconstructed space: it comes to life through the visitors' encounters with one another, extending from inside the museum to the world outside. This book introduces the artist and the ideas behind the exhibition to a broader audience through interviews, dialogues and an introductory essay by Louisiana curator Marie Laurberg. Other contributors include Niels Albertsen, Pireeni Sundaralingam, Timothy Morton, Lone Frank, Andreas Roepstorff, Minik Rosing and the EU commissioner for Climate, Connie Hedegaard.
