The Cross-Eyed Pianist 
What about Ingrid Haebler?
Either of Pollini or Kovacevich I would have thought were essential.
This list can not be complete without Radu Lupu ‘s recording who is known for his Schubert recordings.
I agree – and the only reason he’s not there is because I couldn’t find a YouTube clip of him playing this sonata
Yes, I agree completely Radu Lupu
Yes I agree Radu Lupu is one of the best for Schubert. If only someone can upload a Youtube of him playing this. I’m sure there are plenty of recordings out there of him playing the Schubert sonatas.
