Thanks very much for finding that.


>However there is no mention of Mr. Kuerti :(

Hmmmm - Trés Bummer....I'll just have to remember where that other article 
was published...drat.


>Mr. Kuerti did write on the pianotech list serve back in 1996:

Yes - I remember this posting.  I had hoped that he would be able to 
contribute with some regularity.  Unfortunately, his tour and performance 
schedules really did not allow it.  Really too bad, I think.  He has a real 
sensitivity for both the technical and human problems of the profession 
that is unusual.  An exceptionally gifted performer, too - able to cover 
solo, chamber and concerto literature with a polish and aplomb that is all 
to rare nowdays.  Re-reading this post, I rather suspect that he would 
still have the same complaints...really touchy, that problem with the 
sharps going too deep.

Thanks again, Don.  I'll see if I can't scare up that other article.

Best.

Horace
