"On the 16th January 1938, in the old hall of the Musikverein, Bruno Walter conducted the Vienna Philharmonic in a valedictory performance of Mahler's 9th symphony. The occasion was special in many ways. Walter was the work's dedicatee, and had given its premiere a quarter of a century before; the orchestra was Walter's own, as it had once been Mahler's; notables, including Austrian Chancellor, Kurt von Schuschnigg, were present in the hall, and F.W. Gaisberg, the pioneering record producer, was on hand with his technical assistants to commit the event to disc. Listening to this extraordinary performance today, one becomes an eavesdropper on a vanished style of orchestral playing: the players, with their studied lilt, their poised rubato and their unanimous portamenti, are speaking a shared local dialect. This is how Mahler himself made them sound, one imagines, and theirs is an artistic tradition, soon to be despoiled, that for a memorable hour or so on that winter evening was still perfectly coherent and intact."
This excerpt is from an introduction by Malcolm Bowie to an edition of Freud's 'Outline of Psycholanaysis' and it prompted my purchase of this remarkable performance which is well represented in Professor Bowie's remarks.
