Only now are we fully aware of the true immensity of Vivaldi's concerto repertoire. The violin is by no means the only instrument he favored: the place of the bassoon in his work catalogue is remarkable for it's size and stylistic homogeneity, as well as for his solistic treatment of an instrument previously confined to the continuo. Seven new concertos here join the twenty-six already recorded in the first four volumes of the Vivaldi Edition, an anthology Sergio Azzolini embarked on in 2009 with L'Aura Soave, and now builds on with L'Onda Armonica.
