This is a great DVD, with great sound, and an impressive performance. Yundi Li's technique is seemingly effortless, and his mastery of the piano are outstanding, especially at his age at the performance. There are very few mistakes (adjacent notes touched) that would be noticed only by a listener who has memorized the works performed. His tempi are reasonable, although occasionally hurried, but not so out-of-control as with Martha Argerich, and not slumped as Claudio Arrau's. His overall performance is awsome.
On the other hand, the photography is totally inappropriate. Watching a classical performance is not the same as watching drama, and the competent photographer usually knows when to focus on the face or the hands. This is terribly missed in this production, and you find yourself almost begging the photographer (so to speak) to show the hands in critical passages. I see that a previous reviewer also mentioned that point. I normally don't look much at credits, but here, I have to mention that the photographers - Walter Hasenfratz, Michael Horcher, Gary Kaul, Christian-Michael Oertel, and Karl-Heinz Zeagler - did an extremely poor job. I gave only four stars for that reason.
