Uhmmmm.  Nikolaieva is one of the greatest Bach interpreters.  In order
to understand her, is neccesarily to erase the concept of "long phrases",
and the concept of speed before than musical rendition.  Her way to
understand Bach goes to "expressionist" (not exactly expressive) side of
it.And being a Russian pianist,she is very rare,since most of the Russian
aproach on how to play Bach,is very similar to the aproach used in USA,wich
is mostly based in long lines(phrases),nice tone quality,and the aproach of
"ornamentation" as an accesory instead of ornamentation as an structure in
itself.  Regards:
