Visitors to the 13th Lyons biennial, which opens tomorrow (10 September), will find some of the wall texts defaced, with scribbles and corrections daubed across the captions. Fear not, however, biennale buffs, as the panels have apparently been amended by the artists themselves. The Berlin-based Johannes Kahrs has, for instance, crossed out a reference in his blurb to Gerhard Richter’s Atlas collection of photographs and sketches, while someone has scrawled “some of this is untrue” on US artist Darren Bader’s spiel (a cheeky move on Bader’s part we assume). A spokeswoman for Ralph Rugoff, the biennial’s guest curator, assures us that the biennial bigwig has OK-ed the arty scribblings, proof indeed that Ralph is as chilled as they come on the (otherwise stuffy) curatorial front.
