This said, it was a slightly nervy first half: the Prokoviev began strongly enough, but the more rhythmically demanding material in the middle sections occasionally revealed weaknesses in the ensemble, even if the final Waltz and Midnight excerpts showed a resurgence in confidence. Similarly, there was a niggling lack of cohesion in the Mozart, within the orchestra and in the way it interacted with the soloist, Saleem Abboud Ashkar. This was not helped by Ashkar's own free approach to Mozart's beautifully wrought melodies, which surely require the minimum of stylistic manipulation to achieve their sublime effect.
