When I first got serious about classical music recordings 40something (cough cough) years ago Janos Starker's Mercury recording was considered the last word on the Bach Cello Suites, full stop. Since then the so called historically informed performance movement has taken over and that has lead to a critical reevaluation of Bach in general and Starker's Bach in particular. No one is claiming it is actually bad, but people are claiming that it isn't "authentic" in the sense that the dance movements don't swing in a way that would actually be danceable. And that is true enough, but I love Starker's approach that emphasizes the architecture of the movements, rather than their "purpose." But, to be clear, I doubt anyone ever actually danced to these pieces.

I have three versions of these recordings, the Mercury CD, Analog Productions vinyl and this download. It was a very early hirez download, I forget where I got it, but it is the best sounding of the three.
