Back in the late sixties, Angle produced a 3-disk stereo LP version .... the first to be done on original instruments and from the original score. The English Chamber Orchestra led by Charles Mackerras. If that weren't enough, the soloists wer Elizabeth Harwood, Janet Baker, Paul Esswood, Robert Tear, and Rafmund Herincx ....an all-star cast if there ever was one for this music. The album is beautifully recorded....both chorus and orchestra, and to this day tops any other version I've heard. I immediately treated my set with LAST record preservative and despite 55 years of playing at least two-three times a year between Advent, Christmas, and Easter the disks remain gloriously pristine.
I don't know anything about this recording....whether it is still obtainable and in what format, but if you can ever hear it much less purchase it, it would be well worth the effort or expense. At the time it was "Album of the Year" material for all the music publications and may put all the more recent recordings into perspective.
