For the 16th Biennale of Sydney, Paul Pfeiffer presented the Vitruvian Figure, an 8-metre-diameter model of a giant stadium designed to seat an audience of one million – the result of his two-year collaboration with Bligh Voller Nield Architecture who designed Sydney’s olympic (ANZ) stadium. Mike Parr’s confronting new installation, MIRROR/ARSE, drawing together 17 videos from the artist’s past performances, received both praise and infamy for its challenging atmosphere.
