Alessandrini has reconstructed a Vivaldi Vespers Service for the feast of the Assumption of the Virgin. Vivaldi wrote many Vesper Services for the Virgin but none of them survive completely intact. This reconstruction is magnificent. It is grand, opulent and highly refined. The instrumental interludes and the Antiphonies are especially notable. This is precisely because in the case of the Antiphonies Alessandrini has "re-shaped" the antique Gregorian chant melodies of the Antiphonies in the form of "ariette", for which there is evidence of such a new style being used in Vivaldi's day. Alessandrini has however re-written them in a style older than that of Vivaldi. This entire reconstruction is very beautiful, highly articulated and elegant. The orchestration of the Magnificat RV 610a has also been re-written for a double choir and double orchestra to great effect. The choir is mixed male and female and not a completely female choir as would have been the case of a performance of the Vespers in the Ospedale della Pietà. The solo singing is exceptional. The psalms which form the body of the service and the other religious works, the Salve Regina ,and the Ave Maria etc. are better than the Robert King recordings of the complete sacred music of Vivaldi on Hyperion. Gramophone has said that the choir in this recording is under favoured, and that there is a slight fuzzy mechanical "swirling" in the sound. Although that it is true that the choir is not dominantly placed acoustically, it is a relatively minor defect and however I do not notice any "swirling" mechanical sound disturbances in the recording. Highly recommended. A classic desert island recording.
