This is a superb account of this Choral masterpiece from the mid-seventies and re-mastered in digital sound.
For somebody who prefers the more traditional style of conducting and playing of Mozart's works, they don't come much better than this!
One can forgive the rather big and full sound generated by the BPO, in typical Karajan style, as opposed to the more recent brigade of period instrument ensembles and generally fast tempi.
Despite this the recording is well balanced and the soloists, chorus and orchestral playing are all top grade.
If you like the interpretations given by Harnoncourt, Hoggward and alike then give this a try and you will find just how good the previous generation of conductors really were....
