So I've got my first solo recital in June, and so far the first half of the concert goes like:
Bach - Partita no. 2
Beethoven - Sonata Op. 31 no. 3
Then after the interval, I really want to do a big big work lasting about 25+ minutes. Ideally perhaps a collection/set of short pieces rather than another sonata, for example. I've thought about Rachmaninoff's Six moments musicaux, but I wanted to hear about other people's ideas

Don't worry about difficulty, I've got a lot of time, and I'll make doubly sure if something is a bit beyond me at the moment!
