This must be the best version I have heard so far and that's includes both performances.
Bernstein's captivating performance behind the pianoforte, in Shostakovich 2'nd piano concerto, is absolutely stunning - is has everything - soul, dynamics, insight, sensitivity, energy and drive!!!
Bernstein knows where it's at and even though it is an older recording, the sound it really good.
(I have to confess that I don't the own CD version - I have it on vinyl) But just wanted to recommend this recording to anyone who cares - this is marvellous!
