For me his studiorecordings of Bach's music are unemotional/mechanical, monotonous in most of his 'Bach 'recordings. I prefer his 'Goldberg Variations Live in Salzbourg' and some others. I once read that Glenn Gould was a practicing beast but in front of public he harmonized what does the trick for me. For me it is ok that some people like his 'Bach' studiorecordings some don't and we can't deny Glenn was a controversial pianist.
Add: if i listen to his studiorecordings of ' Bach' i have to dose them. I can't listen to all of his 'Italian suites' at once par example. Do you recognize that ? The record or cd you've played is more balanced because of different pieces.
