I got these concertos because I have so much respect for Daniel Barenboim and Otto Klemperer. Barenboim gave me the best performance of
Brahms 2nd concerto with Celibidache and the Munich Philharmonic that I have ever heard anywhere anytime. (Apparently that 1995 performance is available only on VHS out of Amazon UK.) To me it was world class and a world beater, for I have never heard its equal. I had to hear it on Youtube of all places! What a meeting between orchestra, conductor, and soloist. That concerto, I would argue, is the mightiest we know in western civilization. But that's all beside the point. Because I love Klemperer too. And here these two, young and old, pling out Beethoven's piano concerti legacy!
I can sum it all up quickly. Great playing. Unexciting. One would think that Beethoven's music played anyway would be exciting. But apparently not. It has heretofore been my impression that it's hard to play Beethoven without being excitable on some level: depth, breath, and length. (For example, I find the Hammerklavier sonata very exciting!) So how can anyone as good as Barenboim and Klemperer and the Philharmonia play these great concerti technically so well but be so glum unmemorable. If I did not know who these two were, and it were up to me to buy the best performances based on discipline, approach, and other things like passion, I would buy the Szell-Fleisher on Sony or the Giulini-Michaelangeli on DG sets over these. However, if you love these two like I do, that's enough reason to just get them and listen reverently. Ah, well, they are played gorgeously.
