Out of a mostly irrational desire to witness two musical greats synergized in one absolutely fantastic display of awesomeness, I’d like to see Yuja Wang perform Rachmaninoff’s sonata. The second one of course. The first one is great too, but let’s face it, for a girl who professes a love for those lyrical, big, romantic pieces, Mlle. Wang can’t go wrong with Op. 36. And with Chopin’s second already under her belt, I’d only find it in the natural order of things. 
Not that she hasn’t already considered it.
