A friend of mine (she's 17 now)..played the following program recently:
Bach: Partita no. 3
Schumann: Carnaval op. 9
Liszt: Sonata in B minor
Liszt: Reminiscences de Don Juan
Along with this, she has played all the Chopin Etudes, a big collection of concertos (including Rach 3 and Brahms 2) ...numerous other works: atleast 10 beethoven sonatas, 5 schubert sonatas.
She can sightread literally 'anything' (and thats true ....she almost sightread the horowitz/bizet carmen for me!)
And to top it all ...she plays each of these works with supreme technical AND musical command ..rarely heard these days! I'm waiting for her to become famous (I'm sure I'll get permanently free passes to all her concerts !)
