Batagov is highly unusual, actually, if you'll forgive me, with an almost Rachmaninov-like heavy, both emotional and spiritual approach, and getting and hearing that recording completely changed the work's appeal for me. I also have or have had Beroff, Hill (now culled), the early Loriod (which I also liked somewhat), and the old Oliveira on Vox, whose recording I don't remember anything about, but whose 'Catalogue ...' I like.
Oooh I didn't know about Batagov. Such a natural fit for this music. Looks like one of his earliest recordings (1989) but still, characteristically slow - even more so than Osborne (and by quite a margin sometimes). Thanks for mentioning him, I shall look forward to this!
At the opposite end of the spectrum would be Momo Kodama, who is a specialist in the French piano repertoire with a crystalline technique. Loriod is always good I think (I like her
Oiseaux, more lyrical than most) but the sound is a bit dated in such a contested field.
