Amazing Solo Piano Recordings


I'm looking to get your oppinions on the best solo piano recordings available. Style or genre is not important as long as the recording is pristine, clear, open and in your oppinion AMAZING! Please if you can, state artist, label, etc., so we audiogoner's can buy 'em!

Detlof, thanks. I was actually in the process of ordering Nikolaeva, but there seem to be different editions:
1) Melodia
2) Hyperion
3) separated into 3 CDs, which look like some sort of budget label

Which of these is considered the right one to get? I think Melodia was the earlier recording than Hyperion. Hyperion is the most expensive, as usual.
Audphile, I only have the Hyperion, I'm afraid, so I cannot say anything about The Russian recording. Thanks for the hint though, I'll go and hunt for it. The Russian is an earlier take I would think, unless Hyperion just bought the rights for it. I doubt this though, because T.N. recorded a lot for them shortly before she died. The 3 CD set I am also not aware of.
Cheers,
Detlof

Alkan - Concerto for Solo Piano (Marc-Andre Hamelin; Hyperion CDA67569). I picked this up some time ago and just listened to it recently. A stunning work; the 3rd movement can be seen here: http://www.youtube.com/watch?v=fKQO2rRv0VA&feature=related
