is this piece enough??

[_chops]

Im going to search for music collage in stockholm, and i schould have three pieces; one classical, one romantic and one modern.
   I think of playing:
   - kabalevsky sonate n. 3 op. 46 (the first allegro movement)
   - rachmaninov prelude g minor op. 23(?)
   - beethoven sonate third movement on the moonlight or pastoral

but i wonder if the prelude is ok? or should i choose a larger piece?

thanx!
