Though, Michelangeli was undeniably the nearest thing to flawless that we can have. Stunning technical control, incredible facility and economy of movement, coupled with deep musicality.
I say Richter was FIRE, Horowitz was ELECTRICITY.
Richter: Bach, Beethoven, Schumann, Schubert, Prokofiev, Brahms
Horowitz: Scarlatti, Mozart, Liszt, Rachmaninov, Scriabin, Tchaikovsky
Does anyone agree with me?
Chopin is a more difficult match...and I have not listened much to their Haydn.
