Had a day off yesterday and did London things. One of the things I had left undone that I thought I ought to have done was visit the Saatchi Gallery at County Hall. So I did that.

I'd seen a lot of the work there before at Sensation at the RA. I didn't like a lot of it then and it still left me cold now, although I'm starting to think Away from the Flock may not be the rubbish that I thought it was to start with. Damien Hirst has got some other pieces there as well. In fact he may have made the best fish tank in the world ever, or maybe it really is a profound memento mori piece as the blurb on the wall said it was.

I managed to control my mounting ire at the work of the Chapman brothers. God I hate their stuff. There used to be a Scottish indie band called Urusei Yatsura which depending on how you translated it was Japanese for something like "Noisy Boys". That's how I think of the Jake and Dinos Chapman - noisy boys. Their art is all about "look at us - we're crazy - we don't care - look at us - please - just look at us - woo". In other words ultimately it's all about them. So when they are displayed near something like Jenny Saville's amazing piece, Plan they can only suffer by comparison. Mind you I sometimes think we get the art we deserve: hence the success of the Chapmans. I hate them even more for that.

There is one quite extraordinary piece on display. Richard Wilson's 20:50 is a simply incredible, transcendent, creative work. The room is full to waist height with black engine oil. There is a walkway into the middle of the room and there you are surrounded by this extraordinary, slightly smelly, sea of oil. But soon you see that the perfectly smooth surface of the oil makes a wonderful mirror, perfectly reflecting the ceiling and walls of the oak panneled room it sits in. Suddenly it becomes dizzying! You could be hovering in the middle of an enourmous space. All sorts of new perspectives are opened up. I found it one of the most profoundly effecting things I had ever seen. Nice concept, nice execution. Well done everyone involved.
