Query: A Must-Have Recording

At once idiosyncratic, tempestuous and strangely moving, Glenn Gould's recording of WTC I is without compare. Having bought and listened to several other recordings of this piece, I will say that while Gould's interpretation may not be the most orthodox one out there, it is by far the most appealing. The only other recording of WTC I that even comes close is Vladimir Feltsman's.
