Thank you smittims for your post.
From Charles Rosen book: In difficult technical passages the problem is to disengage the mind and allow the body to take over on its own. This is certainly why Liszt advised his students to read a book while practicing as Moriz Rosenthal reported. Only when one can play in tempo the skips in La Campanella or the octaves at the opening of the development section of the Tchaikovsky Concerto in B flat minor while thinking about what to order for dinner, can one pay attention to the interpretation.
I can add that the less I think the better I play (this is my experience).

 I was surprised that Gould found ectaves difficult to play (because he was sitting too low). When he recorded Liszt's arrangement of Beethoven's Symphony no 5, he first played some of the virtuoso octaves in the right hand by using boty hands and overdubbed the left hand afterwards. Ravel also did not use as much octaves in his music and he also sat low.

I listen to recorded music less and less - I want to see and "feel" a live performance,  and the difference when you only have a cd is incomparably less than it ought to be.  I do listen to cds - but as a kind of "poor compromise", a reminder of what perhaps part of the performance was?

Obviously because of her own personal circumstances, Evelyn Glennie probably has more to share about "feeling" music in your body than most, so what she has to say is of exceptional value in that regard... probably the rest of us have lots we could learn there?
