Hmmm, I don't know about a late Scriabin for this type of audience. If it were me, I would probably do several shorter pieces of various levels of oomph, dissonance, and energy rather than an 8+ minute Scriabin #9.
I'm thinking something more along the lines of:
*1-2 of Scriabin Op. 11 preludes
*the Albeniz-Godowsky Tango or any of Lecuona's Andalusia Suite
*Rach's Moment Musicaux 16/4 (the presto)
*Maybe something fun by Gottschalk, Gershwin, or Joplin
Good luck! Sounds like you'll have fun regardless! Let us know what you end up playing!
Thanks for the thoughts!!!! I do love that Lecuona

I picked 9 not only becuase I thought it might be the most accessible for them but because its only around 9-10mins long....(maybe too long??)
The point I suppose was to expose this kind of audience to something really different that they wouldn't have heard before. I can play the Janacek 1/x/1905 which I thought of but it doesn't really have the 20th centuryness (ok not really a word!) that I was looking for. I have quite a bit of Bartok etc but I thought something like the Out of Doors Suite would be more of a no go zone than the Scriabin!!
I am keen for a 20th century sonata that is around the 9-10 min mark and (aside from the length issue) not something like the Barber, Bartok, Prokofiev's, Ginastera's or Rachmaninov's which get played quite a lot, and to be honest, I am very keen to expose the audience to some Scriabin...
too much to think about.....!!!!!
thank you so much!
