"...One of the best available: plainchant sung with great natural flair and   sensitivity". The Church Times
The liturgical seasons of Advent and Christmas contain some of the finest   music of Western Christianity. Three Masses are celebrated, each one marking the   progression of light, through sunrise, to the brilliance of full daylight. 
Advent is a time of preparation, in the first place for the coming of Christ   at Christmas, but also for his Second Coming on the Last Day, to judge the   living and the dead. Both ideas are present here ranging from a simple   unpretentious hymn composed in the 9th century to the well known Advent prose   Rorate Caeli Desuper, a comparatively late chant. 
A unique and seasonally different disc, performed by the renowned ensemble   Pro Cantione Antiqua, world authorities in this   field.
