Well, really a case of brain-dead habits.
The performance is unusual, to say the least. The orchestra making no sound when the loud surprise chord is supposed to come, and then, the next time through, shouting instead of playing the chord.
And is there even a word about this in the liner notes? No. They’re just the usual (and maybe in this case more than usually turgid) musicological exegesis. When, right before our ears, something not usual is going on. Wouldn’t we want to know something about it? Mark Minkowski is the conductor. What were his thoughts about playing the surprise that way? Has he done it before? Will he do it again? Does he have other surprising plans for any standard repertoire piece? What did the musicians think?
But then classical CD liner notes are mostly brain-dead. Almost never do they talk about the performance. Only the piece. As if the only purpose and only meaning of the performance was to reveal the glories of the piece, and (implicitly) as if any difference from one performance to another — and any ideas the musicians had — mattered very little.
Which — metaphorically, at least — begins to show why the many recordings of all the standard pieces seem to blend into a blur. Especially for all the newcomers we hope to attract.
