Wilhem Kempff is an old sloppy cheese, sorry, but its so. Barenboim is supreme. Also Gilels, Brendel etc.
And you're a young neat turd.
For me its Claudio Arrau hands down. I think my brain must just be slower than most people's or something, because I can actually hear music go by when he plays. When most other artists play Beethoven, it sounds like it is on fast forward to me. I feel like Barenboim sometimes plays it a bit slower too, I've heard recordings by him that I like. I also own Richard Goode's complete cycle of sonatas. I like them too, but he's definitely tending towards the fast forward side of things.
After watching Valentina Lisitsa videos on youtube I have to say she is the best Beethoven and Rachmaninoff Interpreter right now.
I happen to find her Beethoven (and most of her Rachmaninoff for that matter) particularly bland. Also, it's hard to base an opinion when she only has maybe 3 sonata's posted on youtube (Three of the most overplayed sonatas: Moonlight, Hammerklavier, Appassionata.) If I had to pick a Beethoven interpreter, probably Arrau or Barenboim.
I still feel very related to Brendel, because I heard him play so many Beethoven Sonatas live and it was just incredible, it was a life changing experience!!
For sure DANIEL BARENBOIM
I have a recording of what I think is a machine playing moonlight sonata 3rd movement and this may sound like heresy but it's the best recording of the piece I've heard..... it's absolutely relentless, there are no pauses (however brief), no rubato, it is consistently swift, perfectly accurate, and every note falls in place with scientific precision. If anyone is interested I could post it, assuming that's of course?Among the human pianists I like Kempf, Louis Lortie and Stephen Kovacevich
I'd have to say it isn't Frederick Rzewski with this 46 minute "expanded" Appassionata!!
Wilhelm Kempff. very nice.
