Ooo tough one. Actually the ones you mention are some of my favourites. I don't like Cziff, though. Arrau is probably my favourite at the moment. That delicious weighty tone...Although there are a few recordings of him i'm not that fond of. Yeah Bolet and Richter (what isn't he good at?) too. I also love Zimerman in the little he's played. I pretty much put his Piano Concerti, Totentanz, Sonata, and some assorted late pieces as exemplary...he just hasn't played that much. Of course there is Leslie Howard, but it isn't that he's that great, just that he has recorded great works that very few have. Past that it gets a bit iffy. The Liszt catologue is huge and all over the place and right now i'm really trying to sort what pianists play what well. I've really been looking into some more lesser known stuff lately. Such a genius composer once you filter out his better stuff!
