In a daring act of historical reconstruction, the curator Germano Celant, in dialogue with Thomas Demand and Rem Koolhaas, has recreated Harald Szeemann's epochal Live in Your Head: When Attitudes Become Form, held at the Bern Kunsthalle in 1969, and installed by Celant at the magnificent Ca' Corner della Regina in Venice in June-November 2013. Szeemann's show was a dialogue with the Bern Kunsthalle, and Celant has reprised its spirit by placing the works in dialogue with the Ca' Corner della Regina--a very different building, in its Venetian grandeur, to the Kunsthalle. This publication is divided into three parts: the first reproduces photo documentation of the original exhibit, the second compiles essays and interviews on Celant's project and the third includes the installation views of the show in Venice. The book is completed by a Register of works included in both shows.
