An immaterial museum, a social sculpture, a laboratory for the museum of the future: this book is an exhibition filled with moments of inspiration on Vienna’s legendary museum in progress. With its projects in public and media spaces, the museum has been operating beyond traditional forms of presentation for contemporary art since 1990. museum in progress uses open spaces as temporary spheres of activity for art interventions, on billboards, on building facades, in concert halls, on television and even on board aeroplanes. When it comes to newspaper art and multiples in magazines, there is no other institution in the world that would have created comparable groups of works in terms of their scope, variety and quality. In much the same way as if it were a laboratory, museum in progress is constantly undertaking cutting-edge experiments with art projects that both contribute in a practical way to the debate on the future of museums and, at the same time, take effect as a sociopolitical action. This publication presents a selection of works from museum in progress’s comprehensive archive – works which seem every bit as relevant today as at the time they were created. The artistic intervention Analogue Encounters by Adrian Paci makes every copy of the book unique, while the double-cover by Lawrence Weiner is meant to be understood in programmatic terms as an invitation to take new paths through the sensory delights of this exhibition in book form every time you open it, & THEN AGAIN.
