Richard Osborne's excellent liner notes tell us that Neville Cardus wrote in the Guardian that a "raving" audience filled the Royal Festival Hall on the night of 6 April 1962 when Herbert von Karajan brought the Vienna Philharmonic to London for this historic concert. These mono tapes from the Music Preserved collection held at the University of York still fizz with the excitement of that evening 50 years on, the last movement of Mozart's "Jupiter" breathtaking in its inner discipline and Karajan's mastery of the long line so evident in the outer movements of the Bruckner.
