One day, a few months ago when I still lived in Pittsburgh, I looked out of the window and I saw smoke from what appeared to be a big fire in a building somewhere in the distance, with fire engines rushing down the streets towards the scene. I probably won’t forget this since at that very moment when I discovered the fire, I was listening to the song Open Fire by Einstürzende Neubauten (whose name translates “Collapsing New Buildings”).
