This was a Quora question. Actually the verbatim question was "What other pianists are there who play Bach similarly to Gould? i.e. quite detached and rhythmic (no rubato)". So I offered an answer:
No one plays similarly to Gould, so let’s clear that up straightaway — if by “similarly to Gould” you mean with a combination of swinging musicality and keen precision unlike anyone on the world stage before him (with the possible exception of his teacher, Alberto Guerrero). I’d dispute your “no rubato” idea, but I’ll take it as shorthand for his unprecedented attention to rhythmic detail.
However, there is one guy out there who plays with a /much more/ pronounced detaché and accent: the Finnish player (and former student of the great Ralf Gothóni): Olli Mustonen. There is no one who plays like him either! He’s got a fair lot of Bach in his rep, so you can get a sense of the differences (or similarities, if you like) between him and Gould. I don’t think of it that way, personally, but simply and needlessly to say I like them both very, very much. If you haven’t heard him, I encourage you to do so.
