This is not just another disc (or, in this case, double disc) of Vivaldi violin concertos, but rather one of very few discs on the market to treat a chronological aspect of Vivaldi's career. In question here are early works by the Red Priest. These concertos date from around 1700 to 1710 and were thus composed prior to the appearance of the L'estro armonico, Op. 3, and La stravaganza, Op. 4, sets that made Vivaldi's name. Most of them appear on other recordings, but many were only recently authenticated. And not very many musicians have tried to draw a portrait of Vivaldi as a young man.
