American artist Rashid Johnson and Russian collector Dasha Zhukova were the unlikely bedfellows to be jointly honoured at Performa’s annual gala this year. Picking up the bill to the glam event – a fundraiser for the long-running New York performance biennial – was Chang, the founder of the Beijing-based Domus Collection (and collector of Johnson’s work). Live art is an expensive business, with little in the way of a market to help it along, and Chang, as president of Performa’s board, has been a major backer. Yet it’s not just cutting-edge work that attracts Chang: he’s a (heavily involved) trustee at the Royal Academy in London, as well as vice chair of the International Council at Tate. Of course this is just the public face of Chang’s patronage. As an avid collector, he is searching out, he once told ArtReview, works that have ‘truth and beauty’; when Chang favours an artist, he becomes a supporter in more ways than one.
