It is more than a film but not exactly an exhibition. Not quite theatre or performance, although elements of both are omnipresent. It has Mongolian shamans, Russian orthodox priests, rabbis, imams and psychoanalysts, if you need to vent. There are meticulously detailed recreations of Soviet-era apartments inhabited by people who only speak Russian. Eminent performance artist Marina Abramović is supposed to make an appearance. (She is one of the project’s many celebrity ‘ambassadors’ who also include physicists and mathematicians Carlo Rovelli and Dimitri Kaledin, theatre directors Peter Sellars and Romeo Castellucci, artists Carsten Höller and Philippe Parreno and the designer Rei Kawakubo, among others.) And, for one euro, a stony-faced barman will serve you watery coffee or a litre of beer. It is DAU, the multimedia art ‘experience’-cum-independent Soviet state that is being hailed by its creators as the art-event of the century and by the French press as a disastrous flop.
