The Austrian artist collective formerly now known as Gelitin(formerly known as Gelatin) is famed for its participatory works and events--a rollercoaster inside a gallery, a singing tunnel, a balcony on one of the twin towers of the World Trade Center, a sculpture made from visitor's frozen urine--presented at shows and biennials internationally since 1994. Exemplars of Nicolas Bourriaud's vision of art as "Relational Aesthetics," Gelitin brooks no humorlessness in its interventions, finding and provoking the "Gelitinesque" wherever it goes. Gelatin's ACB gathers documentation of the group's projects since its formation in 1993, and serves as both an overview of the group's oeuvre to date and a foretaste of projects to come. Photographs, sketches, models, artist statements and essays make this first comprehensive publication on the collective an uplifting Gelitin gesamtkunstwerk in itself.
