There are a lot of superb recordings of Schumann Piano Concerto that is not showy at all but that is full of introvert fantasy, which means that this is a very difficult concerto for a pianist to bring off. I am always having a feeling that when one plays Schumann, he/she has to play with solid technique while he/she has to be "off the ground" almost to reach insanity. Really difficult.
Anyway, her playing in the concerto is very solid and her planning is so clear-cut, but she could not really reach such insanity or fantasy. That is sad, because I know that she could have been reached there as she did in Schumann "Waldszenen" on Deutche Gramophone and Erato labels.
I like her "slowness" that is sometimes criticized by a few piano listners (who I think tend to judge pianists by their fast fingerworks), though. Such slowness gives her playing soothing beauty, a virtue that I am having a hard time to find in any other current pianists.
In the quintet, Pires is radiant, inspired, and full of musical intelligence. Her playing is clearly driving all other players, especially in the majestic last movement.
Even if you do not like her concerto playing on this CD, please do not push "stop" there.
