I am visiting the child of two pianists, and both of her parents loved Murray Perahia. The concensus is that he is absolutely without ego. If you love Vladimir Horowitz or Glenn Gould, Murray Perahia is the opposite. His Bach is especially nice. Every note is part of the phrase.
And what is the secret of music? Knowing where every note goes. Every note must live. Every single note is important and has its place in the musical phrase. This is where I went mad for Cecilia Bartoli. For a pianist this is understood and expected. For a singer it is very unusual. She does this.
