Tartini: Violin Concertos Vol 16 / L'arte Dell'arco, Composer: Giuseppe Tartini, Performer: Carlo Lazari, Federico Guglielmo, Conductor: Giovanni Guglielmo, Orchestra/Ensemble: L'Arte dell'Arco, Number of Discs: 2 That these musical treasures have lain hidden away from humankind for so long is scandalous, and kudos to Dynamic and L'Arte dell'Arco for bringing them out of the vaults and on display. This is Volume 16 - CDs 26 and 27 - in Dynamic's massive edition of Giuseppe Tartini's complete violin concertos, all performed by Italian chamber ensemble L'Arte dell'Arco. No indication is given either in the otherwise informative booklet or on Dynamic's willfully uninformative website as to how many more volumes are due to be released. So far a magnificent 115 concertos have appeared. Precisely how many that leaves is rather a debatable point. The difficulties raised for musicologists trying to establish a chronology of Tartini's works by his practice of leaving autographs undated is often discussed in liner and program notes, but what is generally not mentioned is the most salient fact - that Tartini deliberately left the dates out, not because it was the vogue, or because he was lackadaisical, but because he usually revised his works, often substantially. In other words, it is not at all unusual for there to be several versions of a piece, and no way of discerning for sure which changes pre- or post-date which.
