Yeah, the first thing that came to my mind aswell.
This is one of my other favourites:

Real shame my browser is at odds with me; my embeddings aren't working. Quite frustrating as I love the piano and want to add to this thread - so bear with me!
Maurice Ravel - Miroirs Suite (movement no. 4 is my favorite, Alborada del gracioso, as performed by Sviatoslav Richter live in Prague [I think in 1965?]):
Alexander Scriabin - Sonata-Fantasy (No. 2) is my fav. of his sonatas; this recordings from a two-disc set set which I like for clarity and the subdued chromaticism (this music is quite mystical/dreamy and at times even the most colorful interpretations can get muddled in key parts):
