Ilona Oltuski offers an in-depth feature of The Brandenburg Duets on GetClassical.org:
“A new score for the concerto, geared to the baroque polyphony, with typically four, clearly distinguishable voices, demanded some omissions of the many clusters of voices, to gain more clarity. The Freiburg Baroque Orchestra’s ‘chamber’ sound, served as point of reference for Bindman’s newly textured hierarchy of the voices in its finalized newly achieved version, which projects clarity, while honoring the elegance of the original score.
The translation of a concerto score for two pianists always bears the complexity of rivalry, of two instruments of the same sonority. It is much less of an intricate task to distinguish differing instruments. So to introduce a more variant sound production within a two-piano version, Bindman wrote differing expressive lines for both players. Particular modifications of the two- piano repertoire, like crossing hands, makes for an interesting audible vitality of blending and differentiating voices, while using the modern piano’s full range of a pianistic orchestration. In order to achieve a full and interesting sounding score, Bindman did not hesitate to lose some of the original score’s rudiments.
She also decided to modify certain sequences, based on their key settings and harmonic ranges, in order to enhance the overall listening experience. The result adds greatly to the two-piano repertoire, which thrives as a four-hand performance –no orchestra necessary.”
