The disc under consideration concentrates on Salvatore's keyboard music, in particular the Responds included with one of three organ masses published in 1641. These are mostly contrapuntal ricercari reminiscent of Frescobaldi, which are interspersed with the Propers of the mass (there is no Credo), here performed in alternatum with plainsong very well sung by the Schola Stirps Jesse. Both here and in the harpsichord pieces that preface the mass, Salvatore shows a distinct propensity for exotic melodic and harmonic progressions, perhaps the result of his early influences. But there are also moments of great beauty (the Toccata di Durezze which accompanies the Elevation) and glittering passage work in such pieces as the variations on La Bergamasca. The positive impression given by Bonizzoni's performances is much enhanced by the instruments he plays, the 16th century Bizarri-Antegnati organ at Ponte in Valtellina in particular possessing a range of colour ideally suited to these pieces. The disc is therefore of special value to those with a predilection for historic organs, but it is also recommended to anyone wishing to explore one of the more obscure corners of the Neapolitan Baroque.
