A very entertaining conversation between the two, probably after having drunk too much coffee. Two main points of interest:
(1) They spend much of it talking past one another and seeming as incompatible as their respective music would suggest, Feldman with his “human” and “emotional” concerns and Xenakis with his “structural” and “architectural” ones.
(2) Xenakis is quite pithy about clearing out some of the baggage that muddies his creativity:
I prefer artistry instead of psycho-analysis because in psycho-analysis… In fact what you do is, you’re trusting on some traces of your memory, something different in your story, and when you think you have left that story, you’re building something different and it becomes your new past.
And this made me think of Stig Dagerman, who had more traces in his memory than most. (See link for details.)
