Ubu, it is clear that Moms has very strong opinions which is fine. He does not like Perahia's Mozart Concertos.
To say they suck is, ridiculous. The Mozart concertos are among my classical music favorites. I have versions of the concertos by a variety of pianists. There is no one "correct" way to play these pieces, and I personally enjoy hearing them played by Perahia, Serkin,
Casadesus, Curzon, Brendel, Fleisher, Rubinstein, and quite a few others. Each pianist brings something of themselves to the music, and hearing a variety of interpretations is, for me, an enriching experience. So, in my opinion, Moms is simply wrong, though reading his posts can be very interesting.
FWIW, a representative anti-Perahia comment from the rec. music.classical.recordings list, where anti-Periaha feelings tend to run high:
"If you want pretty, soft-grained, dresden-china mozart, then Perahia's your man. Personally I like a little more testosterone in my Mozart than Perahia's willing to provide."
Such folks can't stand Uchida either, for similar reasons.
Perhaps a jazz illustration might fit with this discussion. I can enjoy the more delicate alto playing of Paul Desmond, and the higher testosterone playing of Jackie McLean. Liking one does not mean what may not like the other.
Yup, I can see all that ... and many times I'm in that boat, too - I mean I enjoy Haskil playing Mozart as much as I do Bilson (and several of those on your list, Peter!). I'd just like Moms to use a word or two more to describe/specify his opinion!
Moms has made his position pretty clear:
Whether you agree with him is up to you.
