I’ve just been to a fascinating evening in celebration of the talks programme organised by Frieze Masters, whereby well known artists, including Phyllida Barlow  and Bill Kentridge and Edmund de Waal, are interviewed by princes of the art world like Wim Pijbes, the Director of the Rijksmuseum, and Luke Syson of the Met.   The idea, which lies at the heart of Frieze Masters, is of crossover between money and fashion, which help to drive the contemporary art world, and connoisseurship, which still more or less dominates the experience of Old Master painting.   So in celebration of this crossover, Gucci had taken over the Italian embassy for the evening.   Instead of a formal evening, it was full of models who had suffered a lifetime of malnutrition and rock music in amongst the tapestries:  perhaps not quite enough to eat.
