Master Series is the title of a line of greatest hits albums, released in European countries primarily by PolyGram International, as well as A&M Records, Deram Records, FFRR Records, Mercury Records, and Polydor Records. In addition, some albums were reissued by Universal Music Group under the Universal Masters Collection and Millennium Edition titles.
The title of the two-disc album, Vivaldi: Vespro a San Marco, implies that the composer wrote a set of pieces comparable to Monteverdi's Vespro della beata Vergine, but the title needs to be interpreted somewhat loosely. The program notes describe the collection of psalms, canticles, motets, and prefatory chants recorded here as an evocation of a service of vespers Vivaldi might have assembled rather than a reconstruction of one he actually ever did. These vespers are distinctly Vivaldian in idiom, but they resemble Monteverdi's in the use of some common texts and in the diversity of musical styles, genres, and performing forces assembled; there is not much of a sense of unity in the traditional sense, but a profusion of delightfully varied musical vignettes, including a cappella chants, solos, ensembles, choruses, and instrumental pieces.
