I have heard several of her 7ths in old live concerts and have
never been knocked out by any of them but it took me some time
to recuperate from the one last Saturday and I'm not sure I
have.

  Extremely gripping, while often very ethereal and internal.
I've just never heard a rendition that made so much sense in the
first two movements, so that the return to the basic 2nd
movement theme that ordinarily annoys me was magical, like a
wistful but deep memory revisited.

   I didn't hear the chord clusters as banged and dissonant but
as parts of chordal melodies under which several other melodies
were competing, all resolving appropriately.  The last section
of that 2nd movement I never expect to hear done that well again
as it seemed almost superhuman. An incredibly intense
performance beautifully structured.
