This the first ever recording of the work Harmonia super vespertinos omnium solemnitatum psalmos sex vocibus decantanda (published in Venice by Gardano in 1579), a collection of psalms for 6 voices by Orazio Colombano (born around 1554 – died later than 1595). • Colombano was Master of Music of the Vercelli Cathedral and he wrotethis monumental set of Psalms for Six Voice for liturgical use. The style largely adopts an antiphonal approach, alternating vocal groups in dialogue. Performed by La Cappella Musicale della Cattedrale di Vercelli, conducted by Mons. Denis Silano. This group is specialized in the research and performance of the hidden treasures found in the archives of the Vercelli Cathedral. Don Denis Silano, a musician and scholar, edited the edition for the performance himself.
