The Wrong Gallery started small – just a doorway in Chelsea, New York, in fact, through whose glass edifice, a whole two-and-a-half feet of gallery was on display. It formed a perfect stage for conceptual pranks: artist Pawel Althamer, for example, hired two Polish immigrants to smash down the door every Saturday. Founded by artist Maurizio Cattelan and editors-cum-curators Massimiliano Gioni and Ali Subotnick, this non-commercial space showed the work of over 40 international bigshots in its three year run from 2002 to 2005, and was temporarily rehoused this year at both Tate Modern and the Whitney Biennial. This year the trio behind this gallery-as-a-work-of-art showed their mettle, curating the Berlin Biennial, with Cattelan proving wrong those who claimed an artist shouldn’t curate.
