"I was always fascinated by the idea of making special instruments for special emotions - instruments that lead us to emotions arrived by their own motions rather than by our control. With those instruments, I wanted to explore emotions and vibrations which have not been explored as yet in music.

I thought of building a house on a hill which makes different sounds on a windy day by the wind that goes through different windows, doors and holes. (Re: Grapefruit paperback edition.)

Then I've met Joe Jones who has been making such instruments for 10 years almost unnoticed. Joe built me 8 new instruments specially for this album which can play by themselves with minimum manipulation. (Turning switches only.)"

"The older you get, the more frustrated you feel. And it gets to a point where you don't have time to utter a lot of intellectual bullshit. If you were drowning you wouldn't say: 'I'd like to be helped because I have just a moment to live.' You'd say, 'Help!' but if you were more desperate you'd say, 'Eioghhh,' or something like that. And the desperation of life is really life itself, the core of life, what's really driving us forth."
