Impressionist Liszt is best Liszt but Funerailles is great. It was explicitly written in response to the failed 1848 Hungarian Revolution. His B minor piano sonata is also the best piano sonata
Favorite Debussy is hard but its probably this, L'isle Joyeuse
Pictures at Exhibition, my favorite recording is with Pletnev but it got taken off youtube so Kissin will do
When your parents tell you banging on the piano isn't music show them this, Three Irish Legends especially the last one you have to smash the piano with both arms
Of course, the honorable mentions--all of Chopin and Rachmaninoff solo piano works
Everything else:
Bach Chaconne the original violin, though the piano version is nice too. Contender for the best thing ever written
Solo Piano: some well known, some not
Everything else:
When it comes to banging on a piano I tend to think of the end of Rzewski's Cotton Mill Blues.
