When I first got these discs over a decade ago, I thought I had the equivalent of the Perahia ECO Mozart Piano Concertos of 1980s vintage, was I mistaken.
You certainly can use the CD to guide your piano studies, but I disagree with the performance as any more than technical execution, as good as my PC reading a MIDI score. And yes, I do play some of the Mozart sonatas.
The Uchida recording is lifeless, with the sound dry and dull. Has it been remastered? It sounds like there is only one range on her playing here, fortepiano. Its devoid of personality, I guess that's on purpose?
As the internet makes musical snippets available, I'd suggest you contrast her performances against many out there who are definitely unlike this intepretation, such as Barenboim or Landowska. And before one considers there is but one way to play Mozart listen to Hess, Horszowski, Fisher, Gieseking and others. There are many ways to play well.
