This version is well recorded with natural focusing on the instruments, particularly the piano. The DVD is far from an essential extra. It only contains highlights from the whole project. Lang Lang's comments on the works and his approach to Chopin are interesting. None of this quite matches Lang Lang's performance of No 2 in this year's Prom but that is not (yet) available on CD. This is overall a good buy. Dutoit with Argerich is a safe alternative if you find Lang Lang's presence too overwhelming.
