I function better in the jungle in Amazonia or Antarctica or Alaska or the Sahara desert. An artificial environment like a studio has never attracted me. I could work in a studio, but I would never really feel at home.

You have to realize that, about 20,000 years ago, there was a cataclysmic event when an entire rock face collapsed and sealed off the cave. It's a completely preserved time capsule.
