Oratorio della Purità packed with audiences on Sunday 26 November on the occasion of the presentation of volumes II and III dedicated to the Archdiocese of Udine of the series Organs and organ-building traditions in Friuli Venezia Giulia commissioned by the Coro Polifonico di Ruda and published by Serassi di Guastalla. After the usual greetings, Roberto Frisano spoke with the curators Andrea Guerra and Lorenzo Nassimbeni who underlined the extreme variety of pipe instruments from our region. Attention was also paid to the instruments devastated by the destruction of the First World War and which for a century have still remained in an inconceivable state of degradation. At the end of the series, two volumes are now missing: the fourth dedicated to the Archdiocese of Udine and the book dedicated to the organ builders active in the region in recent centuries.
