I'm applying for youngarts and I really need help?

I just moved so I have little option of asking my piano teacher for
help with this, here's my program:

Beethoven sonata no. 8 mvmt 1
Bach prelude and fugue c minor book 1, no.2
Chopin Ballade no.1
La Campanella Liszt

And then I have to play a piece that represents minimalism, atonalism,
serialism, or something to do with 20th century. I cannot stand these
crappy pieces that I'm finding and I'm going nuts because I cannot
find something that's 5 minutes that I can learn quickly that I can
tolerate.

I found some pieces that I sort of like, but they're for orchestra...
so I need to find something quickly because I have about 3 months to
learn and record- then turn it in.
I hope my list of other pieces is decent. I've only played for 4 years
so this is all I can handle.
