So, are you familiar with any of his pieces that aren't much more difficult than Noel and Le baiser and that would actually sound good performed together?
Or what about one of the Préludes? - they're very early pieces, of course, although already on the way to being distinctively Messiaenic...Best,Alistair
Play Xenakis' Evryali
Hah. A more plausible suggestion would be the Dusapin etudes (for a student of Messiaen). The Fantasie Burlesque and Rondeau are really good too, and not that difficult.
Dusapin was Xenakis' student.
How would go about getting these Preludes if Durand hasn't even published them yet? Not everyone has your alleged connections to scores in the pre-publication stage.
Beg for them from Marilyn Nonken. How do you think I got them?
