No, not familiar at all.
I have seen his recordings on Spotify etc, but he is of the Chopin, Rachmaninov, Liszt solo piano axis while I am of the Beethoven, Schubert, Mozart persuasion.
As such all I can really say is 'Golly, he can play fast'.
Listening at the moment to the Transcendental Liszt studies. Golly, he really can play fast.
If he recorded the Liszt piano sonata, or Rach PC3, both among the rare exceptions where I am really into the CRL axis, then I would find more of interest to me.

I completely agree with your comments on the Liszt - it's all very technical but rather lacking in soul and musicality.

The Rach 2 is another interesting one as it also made many 'best of year' lists but I'm struggling to listen past the first movement. Maybe it improves after that but he's lost me already - I find it almost brashly romantic, in a 'Brief Encounter' kind of way; his playing and that of the orchestra for me make it sound very hackneyed and cliched indeed. It loses all of the finesse and subtleties that it can have in the right hands. My favourite two recordings of this are the Ashkenazy and more recently Khatia Buniatishvili - they are much more focused on the inner workings of the music rather than the surface emotion.

Maybe! He must be better than this.

I think DG are doing a very good job 'selling' him.
But I am surprised by some of the plaudits these releases are getting.
