In the midst of Advent, Cor Cererols arrives at the Palau de la Música to present, under the baton of its director, Marc Díaz, a reconstruction of the liturgy of Completes by Cererols, placing them in the context of the Christmas celebration and adding to the composer's music his own fabordones, Gregorian chants and motets, as well as carols corresponding to the celebration. The programme will be completed by works by Victoria, Palestrina and the contemporary Norwegian organist and composer Kjell Mørk Karlsen.
