Just by chance I recently replayed my copy of a Koch Schwann CD (3-1448-2H1), which contains the last three movements of Bruckner’s Eighth Symphony, with Herbert von Karajan conducting the “Preussiche Staatskapelle”, recorded in Berlin’s Haus des Rundfunks in 1944. The second and third movements, recorded in June of that year, are impressive enough in beautifully rounded mono sound, but the last movement, recorded in September, exists in glorious stereo. This movement and a complete recording of Gieseking playing Beethoven’s “Emperor” Concerto, also in excellent stereo, are the only significant survivors of the work of the engineer Helmut Krüger, who developed the technique of stereo recording during the later stages of the Second World War. Such was the sound quality of that last Bruckner movement, even to my battered old ears, that I was left to ponder once more on the sad fate of German wartime stereo.
