Just curious which pieces everyone's learning.
For me it is:
Brahms, 2nd Rhapsody
Chopin, étude op. 25n2
Bach, WTC1 P&F 23 in G sharp minor
Bartok, Allegro Barbaro
The Allegro Barbaro is pretty epic win. It's easier then it sounds/looks, until you get to the good tempi. then its a fun game to practice the displacements.
