At last, the Monstre Sacré is finished...
This 17th sonata takes its inspiration from the Book of Revelation. I felt the all-encompassing visions of heaven and earth, written down by St. John, called for a musical adaption that's equally large-scale and extensive, both in dimension (up to 80 minutes of playing time) and in expression (dynamics ranging from ppp to ffff, suitable only for the largest cathedral organs). It's my most ambitious and complex composition for organ to date, and it offers a tremendous challenge for the player, whom I hope will be rewarded by its musical and spiritual content.

  • The first movement Praemonitio (forewarning) paints the chaos of the pre-apocalyptic world, and the misery and anxiety of its inhabitants, expressed by the Gregorian antiphon Parce Domine, which is used thorough the movement.
  • In the second movement, both a massive, abstract quadruple fugue and a vivid sound painting of St. John's visions, another Gregorian melody manifests itself amidst the turmoil, Da Pacem, Domine, give us peace, o Lord.
  • The finale, Civitas Dei (The City of God) is a long and virtuoso toccata based on the sequence Lauda Sion Salvatorem, exploiting all the splendor and majesty the organ has to offer.
