The conceptual artist Ai WeiWei illustrates the schizoid society that rapid change has produced - sometimes by reassembling Ming-style furniture into absurd and useless arrangements, or by carefully painting and antiquing a Coca-Cola logo on an ancient Chinese pot.

The '80s market was only a Japanese market. It was the Japanese outbidding each other for the most expensive works of art. When the Japanese economy went down the tubes, there was no one left to pay the prices that have been recorded for all of those works.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.
