Others mentioned Xenakis, Babbitt and a handful of other names.

I don't know about Philidor, but if this list so far is representative,
it doesn't do much to counter an impression that chess-obsessed musicians
are excessively mathematical and impersonal.  That may be an unfair rap
on Schoenberg, who is far more emotive than many of his contemporaries,
but Xenakis and Braxton (an avant-garde jazz composer given to using
incomprehensible diagrams in place of track titles and who has often been
accused of non-swingingness and excessive intellectuality) certainly
contribute to that potential view.

I'm not sure if that's the point Andreas wanted to make, but it can't be
where he thought this was heading.
