One of the highlights of the 1956 Mozart Week was the concert, which brought together Herbert von Karajan, Clara Haskil and the Philharmonia Orchestra London. Karajan knew how to project the qualities of the orchestra using the pieces he selected. The slow introduction of the Symphony No 39 gave him an early opportunity to demonstrate the precision and aural splendor of the orchestra. Those listening to the Piano Concerto No 20 experienced an enchanting hour with Clara Haskil at the piano. On no other occasion did she play the slow movement in such a calm and heartfelt manner so expressively, as on that evening. In the slow movement, above which hung a “frisson of eternal beauty”, the artist managed to excel herself. Now, this historic concert is available on this release.
