Complines are the final prayers of the day in what is known as the Liturgy of the Hours in monasteries, still celebrated today. This is an office said just before bedtime, and it is likely for this reason that the chosen texts for setting to music are unusually evocative, suggestive, and almost magical. These are texts where the fears of the night are expressed, where monsters and the fear of darkness are spoken of. In others, with beautiful words of peace and trust like the Canticle of Simeon, it reveals the need to feel accompanied and protected during the hours of slumber.

While the polyphonic renditions of this liturgy have fallen into disuse over time, in earlier centuries, they served as inspiration to compose brilliant and unique choral music. The Double Choir Solemn Compline by J. Cererols (1618 - 1680), now recovered by Cor Cererols, are a rare and beautiful example of this ancient tradition. The fact that we are unaware of the exact feast for which they were written, far from discouraging us, allows us to envision their use for a wide range of celebrations,complementing Cererols' majestic polyphonic compositions with works ranging from the earliest Gregorian chants to contemporary avant-garde.
