"To approach Bach, one has to realize that 100 years after Bach’s death, Bach and his music totally had been forgotten. Even while he was still alive, Bach himself believed in the polyphonic power and the resulting symmetric architectures of well-proportioned music. But this had been an artificial truth - even for him. Other composers, including his sons, already composed in another style, where they found other ideals and brought them to new solutions. The spirit of the time already had changed while Bach was still alive. A hundred years later, it was Mendelssohn who about 1850 discovered Bach anew with the performance of the St. Matthew Passion. Now a new renaissance began, and the world learned to know the greatness of Bach. To become acquainted with Bach, many transcriptions were done. But the endeavors in rediscovering Bach had been - stylistically - in a wrong direction. Among these were the orchestral transcriptions of Leopold Stokowski, and the organ interpretations of the multitalented Albert Schweitzer, who, one has to confess, had a decisive effect on the rediscovery of Bach. All performances had gone in the wrong direction: much too romantic, with a false knowledge of historic style, the wrong sound, the wrong rubato, and so on. The necessity of artists like Rosalyn Tureck and Glenn Gould - again 100 years later - has been understandable: The radicalism of Glenn Gould pointed out the real clarity and the internal explosions of the power-filled polyphony in the best way. This extreme style, called by many of his critics refrigerator interpretations, however really had been necessary to demonstrate the right strength to bring out the architecture in the right manner, which had been lost so much before. I’m convinced that the style Glenn Gould played has been the right answer. But there has been another giant: it was no less than Helmut Walcha who, also beginning in the 1950, started his legendary interpretations for the DG-Archive productions of the complete organ-work cycle on historic organs (Silbermann, Arp Schnitger). Also very classical in strength of speed and architectural proportions, he pointed out the polyphonic structures in an enlightened but moreover especially humanistic way, in a much more smooth and elegant way than Glenn Gould on the piano. Some years later it was Virgil Fox who acquainted the U.S. with tours of the complete Bach cycle, which certainly was effective in its own way, but much more modern than Walcha. The ranges of Bach interpretations had become wide, and there were the defenders of the historical style and those of the much more modern romantic style. Also the performances of the orchestral and cantata Bach had become extreme: on one side, for example, Karl Richter, who used a big and rich-toned orchestra; on the other side Helmut Rilling, whose Bach was much more historically oriented."
