Hi guys!
I really need some opinions for my audition

which will be in about 10 weeks!
And I'm preparing these -
Bach BWV 875
Mozart K570
Rachmaninoff op. 23 no. 5
Gershwin The Man I Love
Chopin op. 10 no. 9
My friend said I had a rather weak choice for the 20th century piece as it was too tonal (and easy). He said most applicants will choose from Ligeti/Kurtag etc. He also suggested Messiaen, but I really have a problem playing atonal pieces from memory. If I have to do something other than Gershwin, would Stravinsky's Tango be a good choice? How about Poulenc's Intermezzo?
