Da liapetz sumwut legendary.
His Liszt CDs on APR are fantastic, and his Vox set is great too.
He played one of the best Benediction de dieu dans la solitude ever. The job he did for the late Liszt works (e.g. the Polonaises and Ballades), including many pioneering recordings, is really worthwile.
I urge you to get some of his Liszt recordings. I do not know very much his non-Liszt discography - apart from the Lyapunov etudes, boring and static pieces that, in his hands, sound like masterworks.
He has many wonderful recordings. I like all the early 30’s stuff.
Sometimes, the playing is a bit too elegant (Liszt Sonata) and somewhat lacking in fury.
