The Serenata a 3, RV 690, is the least familiar and in certain respects the most enigmatic of the Vivaldi serenatas. The sole surviving source is the autograph manuscript of the score, preserved at the Biblioteca Nazionale Universitaria of Turin. Many of the questions surrounding the origin of Vivaldi’s score remain unresolved. When and where was the serenata composed? Which patron hosted it? On what occasion did it receive its premiere? Vivaldi expert Federico Maria Sardelli performed the rarely heard work at the Barga Opera Festival 2021 and subsequently realized the present recording.
