What's wrong with modern art?

Will Self explores what's wrong with modern art. "I've been responsible for a fair amount of absolutely total nonsense in my time", he writes, but says most contemporary art is little more than "overvalued tosh and useless ephemera". Instead of a world where Russian oligarchs "buy artworks by the metric tonne and plaster them on the walls of their vulgar houses", he calls for a genuine understanding of art where - once again - we become "capable of conveying and explaining the subtle ambiguities of genuine art".
