i should get to know these 
2,3,4,5,6,7,8,9, are the best.
Esp 3,4,5,6
infact 1 is my current favorite now, absolutely stunning piano writing. The only recording of the complete set is the one shared by Samaltanos and Sirodeau, pretty well done for such an unknown set of works.
Yeah, I really need to hear more of these.
To help you with the process Ive uploaded the first sonata in the Recs section. Only a short work but worth repeated listens for the sheer quality of the piece.
