The new surgically-enhanced Art Moscow has shrunk perceptibly. In fact, it would be even smaller had not Guelman Gallery occupied three spaces and Kaj Forsblum, from Finland, two. For whatever reason, the space freed up hasn't been occupied by more interesting galleries from abroad; since Volker Diehl set up in Moscow we have to count him as Russian, so Forsblum is now the only major foreign participant. Why? Maybe the Art Moscow pr is to blame? I get invitations to participate from all sorts of fairs all over the world, but nary an email from the Art Moscow. Or maybe the show is the victim of the art world's perceived wisdom: that there are only three or four events where you can count on making money (Frieze/Zoo in London; Art Basel in Switzerland and Miami; the Armory Show). I also wonder, prompted by an incident affecting an artist whom I have shown in London, the Latvian photographer Arnis Balcus, whether the fair is victim to creeping embourgeoisement. Work from Balcus's series Flowers was due to be shown on the Riga Gallery stand, but the organisers requested it be excluded. Below, a Balcus from the prohibited series. No black cock in Moscow, pliz!
