The Best Piano Works of the 20th Century

I was looking for pieces for solo piano, but I wasn’t clear. Regardless, there are some great suggestions here. Nancarrow is an excellent suggestion. I’ll add Prokofiev’s Piano Sonatas. 

I overlooked Prokofiev’s. :-(  FWIW I highly prize Chiu’s 9 CD traversal of all of his music for solo piano including some transcriptions. I also overlooked Rachmaninoff’s 24 Preludes and Sonata #2.

+1 on the Chiu suggestion

my additions would be the Shostakovich piano sonatas and something else I’m really into which reminds me of the Rzewski is Maxwell Davies’ “Farewell to Stromness” from The Yellowcake Review

I'm partial to early 20th century 'modern' piano-e.g., Scriabin.
Spare, angular, but not atonal. 
 But the one of the best artists who 'covered' him was his son-in-law and the recordings--from Russia- are not great. 

Should we add particular interpretation we like? There are some recordings of a certain work that give an overall better impression. I am not talking about "audiophile" standards, but about the music itself. of course, it will depend on a personal taste, but it may be worth a try.


Having said that, all my favorites are from way before 20th century, save for Satie, so I cannot even participate. I will peruse this thread to explore, though. Thanks everybody.
