“Who are pianists that you think more people should know about?”

(1) Alexander Slobodyanik.  Ukranian pianist, 1941-2008.  Hailed as the most jawdropping phenom since Ashkenazy when he debuted at Carnegie Hall in 1968.  Powerhouse romantics interpreter, no limits whatsoever.  I have his Liszt B minor Sonata and Chopin Etudes on vinyl circa 1973/74.  Amazing.  He remained USSR-based into the late '70s and the dissolution of cultural ties with the west following the 1980 invasion of Afghanistan kept him out of the US (where he ultimately settled) until 1988, which had a derailing effect on what might have been a towering career.  

(2) Jan Lisiecki,  Might not fulfill the criterion that "more people should know about" because he's gained traction...but more people should know about the fully mature artist he's become (at 28).  He shares in common with Kissin his recognition as a prodigy (signed by DGG at 15!)  I saw his March 2024 performance at Carnegie...may be necessary to bring in contractors to repair the roof, because he blew it off.

As a demonstration of the fact that God does not distribute gifts evenly - both of these dudes were/are movie star handsome on top of everything else.

There are many interesting out of print recordings in thePianoFiles.com. I was surprised to find these rare recordings of Marian Filar who's Chopin playing is of the best I've ever heard.
