These days, I listen to Josep Colom a lot, I think he's great. But in general for me too, it's Glenn Gould who first comes into mind among the many others. I tend to be forgiving with respect to the idiosyncrasies of geniuses like him (like his singing, etc.), I find that "part of the package", and it doesn't bother me. Genius often comes with very strong opinion about others, and thus "unorthodox" interpretation of their works -- I guess we all know that about Gould. One of my favourite recordings by him is Haydn's late piano sonatas, escpecially the C Major Hob. XVI:48. If it could be quantified at all, I wouldn't be sure how many percents are Haydn in that recording, and how many are Gould, but I have a feeling that it's about as much Gould as it is Haydn (of course, just like none of us can know how a recorded music sounded live, unless you were there [and even then...], we may never know how Haydn played that sonata to himself one late night back in those days, whether Schiff is closer to him than Gould, etc; so I would say the piece is up to strong interpretations -- as long as you enjoy it).
Great classical pianists
Alexandra Dovgan is the pianist of her generation.
In the last century there was Richter. Today Trifonov. Now a new phenom. What is it in the Russian water that produces such giants of the keyboard?
We enjoy all great pianists. Rubinstein, Pollini, Argerich, Backhaus, Kempf, Michelangeli, Schnabel, Pogorelic, Gilels. Please add your favorite to this embarrassment of pianistic riches. But there is primus inter pares.
