The organ at the Church of San Carlo in Brescia, Italy, dated 1636, was long attributed to a member of the famous Antegnati family of organ builders. It is now thought to have been built by someone of the Antegnati School. Sebestyén used this instrument for Melodie di Natale on ANGELICUM and for the Speth toccatas and Walther recital on BOÎTE À MUSIQUE (BAM).
