Last night when everyone else in the household went to bed, I stayed up to listen to this with a copy of the public domain score (from MuseScore.com) in front of me.

Looking at the score, one obvious note is the utter absence of dynamics and tempo markings. Which leaves considerable room for interpretation. The range of the 30 variations (plus the base Aria and final Area da Capoe è Fine) allows the pianist to show her range, and Ishizaka provides something to hear. As expected, she does not make the same choices as Gould. And she does not seem to be in as much of a hurry as Gould was. And the recording became a delight as she worked her way through the variation, each with its own feel, even with each repeat.
