Any particular views on those boxsets please ? Thank you very much.
The Poulenc Le Sage is good, but not on par with anything done with Alexandre Tharaud (his chamber set on Naxos is self-recommending). Also, in the piano concerti, it’s difficult to beat the Sylviane Deferne and Pascal Rogé performance of the
Concerto for Two Pianos and Orchestra and Rogé in the
Piano Concerto. Rogé is also quite good in the solo piano music. Gieseking’s Debussy is overrated...there I said it now people can hate on this post with great outrage.

But seriously, Samson François is much more attuned to Debussy IMHO and while we’re speaking of older Debussy pianists, Michelangeli’s performances need to be heard to be believed. They're just
that good. I don’t know anything Mandelring’s Shostakovich SQ cycle since I own too many as it is: Brodsky, Borodin, Emerson, and Pacifica. So I don’t really feel I need any more at the moment. I don’t really care anything about Tchaikovsky, so I can’t comment on that Postnikova set.
