Antonio Caldara is one of those composers from Italy whose career brought him to Vienna, where he composed and performed mainly oratorios. He started his career in Venice where he was born in 1670 and where he studied with Giovanni Legrenzi. Being an accomplished cellist he was probably a member of the orchestras of the opera houses in Venice. In the 1690's he published two collections of trio sonatas, which are following the example of Corelli. His first opus, published in Venice in 1693, was again published by Roger in Amsterdam in 1698, a sign of their popularity.

Bononcini was a contemporary of Handel and for the few years he stayed in London the two men were - presumably - friendly rivals, as both had operas staged in turn (together with a few other composers) at the newly formed Royal Academy of Music. Bononcini was an exponent of the Arcadian style of Italian opera, Handel the high dramatic. It is very much that pastoral, Arcadian approach that is on display in the music on this CD.

Francesco Gasparini was active in Italy during the late seventeenth and early eighteenth centuries; he served for a time at the Venetian orphanage called the Ospedale della Pietà, where he hired the young violinist Antonio Vivaldi. His music has been mostly unheard for several centuries, and this high-quality revival will be welcomed by Baroque vocal fans and those interested in Vivaldi and his world. Included are a quartet of cantatas, two for soprano and alto, and two solo cantatas, mostly with a pair of violins and continuo. Despite the plural "sonate" promised by the disc title, there is only one sonata, placed in the middle of the program as a kind of intermission.
