The thirty concerts for trumpets, oboes, strings and continuo, performed here, represent the first integral recording in situ of these composition. Only the original versions of all the authentic and signed manuscript pieces were considered for the recording. One of the main purposes in this recording was to reconstruct the acoustic effects of these compositions in the Basilica, respecting the original arrangement of the musicians in the cantoria around 1700. With the few iconographical documents and the original partbooks of the compositions it was possible to reconstruct accurately the authentic instrumentation and placement of the musicians in the choir. The result is stunning. The Cappella di S. Petronio is the oldest musical institution in Bologna: founded in 1436, it has curated the basilica's musical activities for five centuries, becoming, in the seventeenth and eighteenth centuries, one of the most important centers in Europe for sacred music thanks to the teaching of first rate musicians.
