Rabbi Akiva is best known for his declaration that "the entire world was never so worthy as on the day on which the Song of Songs was given to Israel." With justice, one could say the same thing about the Bruckner Eighth whose Kerygma is just as sacred.
Karajan strongly identified with the Bruckner Eighth throughtout his life and every one of them offers instruction: the stupendous 1944 torso with its finale in stereo; the 1957 recording with the Berlin Philharmonic [overseen by Walter Legge, no less]; the 1976 re-make with the Berliners; the concert staged in St Florians itself in the late 1970s - and finally, the recording / video made in 1988 when the end was in sight.
As far as I can tell, this DVD is near identical to the CD offering on DG. Whatever avenue you chose, it is a mandatory acquisition for any self-respecting Brucknerian. Herbie was clearly on his last legs in every way when he made this recording - even so, defiant of twilight, he poured the last of his lifeblood into this performance (the Bruckner Seventh that followed is not in the same league). As Richard Strauss noted, following scripture: thus is the body dead but the spirit is life.
The Ninth, recorded in November 1985 with the Berlin Philharmonic, displaces neither the '66 nor the '76 performances, both of which are on CD. For whatever reason, Karajan was out of sorts on the night - marginally; the coda to the first movement, for instance, lacks the hushness that makes the two predecessors so memorable; in recompense, the Schezro is more diabolical than Satan himself. The finale is a much more of a valediction the Lied von der Erde - here, Karajan was back to his best.
All in all, this DVD deserves to be in your collection. As per most of the Karajan films on Sony, the direction is unimaginative but who cares when the music-making bestrides this world and the next.
