Commercial: You are listening to

hollywood, a photo by kara brugman on Flickr.

Tremendously late to this I know, but it is rather wonderful.

Take an epic photo, a restless ambient soundscape and a live police call feed. And, right there, you have the pulse of a city.

I'm still slightly amazed no-one's managed to knock one together for London yet.

I also thought it might be a great way to showcase any form of spoken word. Can you imagine radio ads, traditionally all squeaky and shouty and chatty and insane, against this sort of backdrop?

I think the juxtaposition would be stunning.
