I have this one. I think ashkenazy is performing these. I know he does some of the etudes on that site.
actually, no. the site's quite changed, and i can't find that old long list of recordings that was there before - now i only managed to find chubrik's own recordings. so, the link above is to chubrik's one, pls let me know if you can find the old list (my russian is a bit rusty

)
edit: never mind, i found it.
so, paris:
https://classic.manual.ru/Rachmaninov/op. 39 with ashkenazy, richter, kissin and rachmaninov!
enjoy
