We Walk Through War Cities and Madness.

• Metropolis - a review by Lawrence Norfolk.

"Polluting, parasitic, overcrowded and violent: cities have always been popular with humans. They've needed to be. From the 35,000 inhabitants of Sumerian Ur, 4,000 years ago, to the current chart-topper - Tokyo, home to 26 million - cities have consistently buried more people than they have produced. They also eat more food than they grow, drink more water than they collect and, the inevitable consequence, excrete more sewage than they know what to do with. But, for all their faults, we like these greedy, incontinent monsters. Half the world's population lives in cities, and that share is growing."

• "His Work Just Bores into You" - a collection of quotes from fellow musicians about cult underground bipolar artist Daniel Johnston.

"Tom Waits - I covered King Kong because it's classic Daniel Johnston, one of the great love stories of all time. My favourite line is: 'Just him and his screaming woman!'"

• Remember that secret Parisian catacomb? The group behind it reveal their methods, means and useage of the underground hideaway.

"Huddled round a table in an anonymous Latin Quarter bar, the group's members - of whom only Lazar wanted to be named - relate past exploits: rock concerts for up to 4,000 people in old underground quarries; 2am projections in a locked film theatre; art and photo exhibitions in supposedly sealed-off subterranean galleries."

• I watched a great Channel Four documentary a few days ago that explored the idea of Live Art. As fashionable as it is to dismiss the idea of Modern Art being a waste of time because it cannot be purchased, exhibited and dissected by a million philosophers, I love the alternative movements that are sprouting up in the inner cities of the world. New York, London, Beijing, Berlin - it's the art of the current age which symbolises how throwaway our popculture really is. Perhaps most people don't like how disgusting that idea can be - that although we are always documenting documenting documenting, with blogs and journals and books and digital cameras...that in reality, what we're documenting is as worthless as the infamous pile of garbage at the Tate Modern. I get it...do you?

• You know this picture if you know modern history. Eddie Adams, the man who took that stunning visual still of the Vietnam war, died this week aged 71. Far too young for a man who walked through wars.
