Barenboim has been working with these wonderful concerti almost all his life, I imagine, and equally is an experienced 'leader from the keyboard', so you would expect these performances to be good, and indeed they are very good indeed. He's using a modern concert grand and there are no eccentricities or particular nods towards period performance, and his orchestra sounds, not small, but comfortably medium-sized - and their sound, too, is the comfortable, familiar sound of the Berlin Phil., absolutely precise, nicely turned, very easy on the ear. The recorded balance is absolutely excellent ; nothing is too prominent or too recessed, and you hear every note. There are no revelations and little that is sharp-edged - Mozart can sound more startling and surprising than here - but I do not mean to damn these performances with faint praise, because there is no doubting the affection or the skill with which they are presented, and indeed they succeed 100% in realising the greatness of the composer's vision. The set comes with an enjoyable DVD of two concerti, K.365 and K. 242, in which Barenboim is joined by Georg Solti and (K. 242) Andras Schiff). Warmly recommended.
