The Best Piano Works of the 20th Century

Thanks tubegroover. I have only one solo piano version, Richter's 1958/60 live recording issued on LP by CBS Records in the late 60's. The performance is great, but the recorded sound is pretty thin.

Very much enjoy Valentin Silvestrov (Ukrainian) music, much of which involves piano.
Would recommend checking out some of his CDs.
IMO: Thread title should be "personally most interesting" rather than "best piano works".

Robert Greenberg, music historian and educator, has a course: The 23 Greatest Solo Piano Works. His choices from the 21st century are:

1. Debussy— “The Sunken Cathedral”
2. Debussy— Préludes, Book One
3. Albéniz—Iberia
4. Ravel—Valses nobles et sentimentales
5. Scriabin—Piano Sonata No. 5
6. Rachmaninoff—Etudes-tableaux
7. Prokofiev—Piano Sonata No. 7
8. Copland—Piano Variations

I have some listening to do!

Ligeti - Etudes
The last one might miss the 20th century (2001) but I always found these very enjoyable. I just realized I don’t have the third book :(

Excellent list as above.  Happy Listening!
