In 1963, Bruckner 4 would be technical challenge to which the EMI production crew rose wonderfully. Wide stereo, V1 V2 split, very left and right, detailed. This work would not have been heard much back then, so this would have been very impressive. Whether that is the case today?
The 4th movement tempo is brisk, almost running pace, which given Klemperer’s reputation was a surprise. Generally, this will not displace your favourite, I would suggest.
But…………. the main problem is technical. When CDs first came out and the older analog stuff was released on CD, tape hiss was the enemy. Here, the climaxes of the movements have been ruined by fading out the Kingsway Hall reverb and ambience as it would have subtended into the tape hiss, too soon. Now I know what’s coming, I can’t play this anymore. Charity shop.
