I can add little to the other reviews, save to confirm that as a collector with all the 'great' recordings (and quite a few odd others), this should be in the collection of anyone who adores the LvB sonatas.
Igor Levit has superb poise, fantastic dynamic control, and evident thoughtfulness in his interpretations. Every time I thought he was going too fast or slow, when I looked at the timings I realised he has Horowitz's ability to defy your senses. Horowitz was ill-matched to Beethoven, but he could balance a mountain on a pinhead, pianistically, and if this is what Levit can achieve now, heaven knows what breadth and depth he will achieve in maturity.
Five stars or more to Igor Levit, but zero stars to whichever dull and ungrateful suit at Sony decided that the CD booklet should comprise a long-winded, grandiose, but by definition speculative essay on Beethoven's psyche during the period of the late sonatas (as if we need another), but not a single word - not one! - about the illustrious young pianist who gave us these superb performances.
