These concertos demonstrate the emerging inventiveness of CPE's musical personality within the trend towards public concerts in the mid-18th century. In fits and starts there are those sparsely etched landscapes which at their best can captivate us. If decorum is sometimes overworked, Bach's originality is even more remarkable given that the ritornello structure inherited from his father's generation, with its alternating solo and string sections, is less easy to sustain in a relatively uncontrapuntal style. Contrast is therefore a key element, and Bach needs a soloist who can discern how the relationship between the harpsichord and the orchestra can be manipulated to good effect. Miklós Spányi and Concerto Armonico, led by Péter Szüts, give wonderfully lucid, flexible and clearly articulated readings. The shading in the finale of the G minor and middle movement of the D major concertos is also energised by a naturally discursive balance, a deft textural palette for which artist and engineer can take equal credit. With such eloquent playing, this volume of world premiere recordings will give the listener more than just an opportunity to refine his perspective on Bach's achievements. It deserves a welcoming audience.
