Horowitz plays Scriabin - (both cds, there are 2 releases with same title), you cannot go wrong with these CDs ..
Martha Argerich plays Rachmaninov 3rd Piano Concerto .. also very decent recording..
Cortot plays Chopin Etudes - the most musical ones I have yet to find , ignore the wrong notes, as he did not care for them..
Rubenstein- perhaps his Rachmaninov 2nd Piano Concerto is ok ...
Hofmann- I would suggest his live recordings from 1937 which includes his amazing performance of Moszkowski's Caprice Espagnol, Chopin's Ballade in G minor, Rachmaninov's G minor Prelude, and his own amazing composition Chromaticon..
if you like Chopin, there's no way on earth you can ignore Marc-Andre Hamelin's complete recording of the Chopin/Godowsky etudes which have been recorded with a technique that surpasses that of anyone that has ever attempted these works.
Sviatoslav Richter also left us 2 gems! Prokofiev's 2nd Piano Sonata and the angelic Scriabin White Mass Sonata recorded very late in his career..
enjoy MR!
