My latest theory is that it's - well, I describe it as, like, being in an apartment with kind of thin walls.

I realized sometime in the early '80s that if I didn't do something - like planning for the future in a way, a kind of pension or something - that if I didn't do something there and then, I was going to be condemned to forever present my three years as a pop star, condensed, as a stage act for the rest of my life. Because that's normally what happens to people in the pop business.

As soon as one of my records goes on, it makes a vast portion of the public nervous. They get spooked by it. To some people who have ears to hear, it's a delightful, refreshing change. But to most of the public, it's a load of homemade-sounding nonsense.
