Mystical chants between the visible and the invisible: The great ancient mystery chants of Spain and Norway. Ensemble Hirundo Maris presents the enigmatic chants of the Middle Ages, Spain's El cant de la Sibil.la and Norway's Draumkvedet. Both convey profound, apocalyptic visions of the world's end and the dawn of a new era, traditionally sung on Christmas night. This album evokes the mysteries of winter, blurring the boundaries to the otherworld, transporting the listener to mystical realms.
