Last August we set up a studio tent at the famous "Wacken:Open Air" heavy metal festival in North Germany. The tent was located right in the center, not far from the main stages. It was blistering hot in there, like a sauna, and it was also very loud, like an amplifier - with death metal raging in from every angle. Imagine working in a gaming arcade, gambling casino or food court in a Bangkok super mall. Imagine the sound pollution. Imagine that times the unthinkable, with people defecating behind our tent - all one hundred thousand of us. By the end of those four days the rash on my forehead was almighty. We must have aged faster. It took me two weeks to recover.
