In this irreverent, gossipy, questioning and amazingly well-informed inside story, BBC Arts Correspondent, Rosie Millard, identifies The Tastemakers, the cultural movers and shakers - artists, dealers, curators, art teachers, entrepreneurs - who have made visual art the culture of choice in Britain today. Over a hundred of these people speak to her frankly about how they pulled off the impossible trick of effectively changing taste. They range from Gavin Turk and Mark Wallinger to Nick Serota, Michael Craig-Martin and Jay Jopling, and from the head of Selfridges to the inventor of 'Changing Rooms', revealing the impact of the visual arts revolution on a much wider stage. This network of links and influences is itself given creative expression in artist Adam Dant's foldout, The Mystery of British Culture, while the participants are photographed making art, or making waves - sometimes both - by Geraint Lewis.
