From this Chapter:
… The design of the Mâche house was completed without IX having seen the site. It fell to Mâche to find a way of realizing the project … adjusting the orientation of the structure and especially the positions of the light-giving slashes … [He] was the one responsible for realizing the structure & making it nourishing ... the result actually is a marvel to be in. The feeling of heightened, otherworldly (other-planetary?) comforting shelter one feels there, in the perfectly lit days and during lantern-flickered light in the evenings, is unique. It is productive of a calm that one can imagine being a near perfect place to work. (Perhaps better for writing than composing in view of how much less “natural” music has become than the words I can simply place on paper as I am now doing.) Perhaps the element-centered experience of this house (sky, wind, sun, rock) would be overbearing, would tend to mark other activities as contrived, too artificial. Would such a place stop rather than start one? (Perhaps both, the start being a re-start to some new place.)

Also from Chapter 1:
Xenakis, though curious and voluble, was not a storyteller: imperious, strongly directed, often ironic, but alive to and warm with concern for those in whom he found interest. There was often a judgment of some sort at the end of an episodic exploration of whatever subjects drifted through our interactions, sometimes cutting, sometimes benevolent, at others unexpected and memorable in its ellipticality. The last time Xenakis and I met in his studio, his final illness had begun to possess him. We had been seeking together sketches, documentation of any kind that related to the desert house that he had designed for Karen and me in the early 90s. Feeling the implications and threads of similar moments – they stretched back decades – and not knowing exactly how to close this interpersonal window, we stood at the Studio door. I turned to leave and he said, not “Take care.” “Glad we could get together …”, nothing of that sort. No, he said, “Be intelligent.” The door closed.
