The Accademia Arcadia was flourishing in Rome at the time Andrea Stefano Fiore, one of Italy's true child prodigies, was there. The wide variety of stylistic influences and superlative quality of his cantatas, from lyrical simplicity to daring harmonic experiment, are confirmation of Fiore's uniquely poetic talent. Giovanni Antonio Giay succeeded Fiore in service at the royal court in Turin, and these world premiere recordings together reveal musical treasure of great value, sublimely documenting the extraordinary musical sensitivity of these rarely heard composers.
