Wolfgang Gönnenwein - opening chorus of Bach's Saint Matthew Passion - like this a lot, even more than the Wöldike
Bernard Roberts - a number of selections from the Well-Tempered Clavier Book 1, including BWV 849 - I like the relatively self-effacing approach. I like the tempo on the BWV 849 fugue and BWV 853 fugue.
Helmut Walcha - BWV 552 fugue (2nd, Alkmaar), BWV 565 (mono), BWV 849 fugue (1st and 2nd)
Marie-Claire Alain - BWV 538 (2nd)
Harald Vogel - BuxWV 140 (Schnitger organ)
