Different renderings of classical pieces can be night-and-day difference. There are some pieces that have been worn grey from over exposure and then you hear that one special version and it's like it is a completely new piece all over again.
Now just imagine you lived during the romantic period of music where the virtuoso's highly personal interpretation of the piece was not only encouraged - it was downright expected.
Even today where the printed note is considered sacrosanct - you'll still find that artists are able to inject quite a bit of their own personality into a piece.
Great example is the Well-Tempered Clavier as performed by Glenn Gould versus Sviatoslav Richter.
…which of course is a good reminder not to make assumptions about domains in which one has limited or no knowledge. I too have spent my entire life in classical music - I’m a collaborative pianist. But I have to guard against making judgements about popular genres which I don’t regularly listen to.
