What has 4 Legs, in the Round ? The question is posed in the New York Times and the answer is U2's 360 production which opens in Barcelona next Tuesday night.

'Everyone who sees it says that it looks like something different,' said Willie Williams, who has worked with U2 since 1982 and co-designed the set with the architect Mark Fisher, a veteran of Pink Floyd and Rolling Stones tours. 'Tintin's rocket. The War of the Worlds. Cactus. Octopus. Claw. Whenever it started to look like something, Mark and I would push it in another direction. But it does look as though it has escaped from a giant space aquarium.'

'Our work is all to do with the logistics of building a very large piece of technical infrastructure in a very short time, and to make something interesting out of it,' said Mr. Fisher. 'Why do people go to shows like this in the digital age? It's for the huge collective experience, the social and spatial and memories. This set will contribute by creating a massive sense of anticipation and delivering an amazing kinetic performance.'
