So says Nicholas Forrest on his Art Market blog.
Nic, or Nick, (he seems to use both) also talks about the current Arte Povera movement and the fact that there is no one superpower 'art market' today, because there are so many markets, with fast-emerging and constantly-changing trends, making it very hard to predict where the big movers and shakers are. At least, that's what I think he means.
Nic does identify Los Angeles as the big up-and-coming market. Whether you agree with his analysis or not, his blog makes educational and interesting reading.
