`Happenings' is the term coined by 1960s avantgarde artists for their own unique type of performance event. Together, they formed one of the most influential experimental movements of the century; yet also one of the least-well understood. Bringing together radical visual innovation with live performance, Happenings galvanised both fine artists and performers. Articles, statements, interviews and essays by and about some of the most influential avantgardists of the era are presented here for the first time since their original publication. They include: * Allan Kaprow * John Cage * Yvonne Rainer * Claes Oldenburg * Ann Halprin * George Maciunas Happenings and Other Acts is a unique and important collection of original material, and concludes with a substantial, specially commissioned essay by Günter Berghaus on European Happenings.
