Chant on the Vigil: Vespers for the Feast of St. James

These beautiful and haunting vespers are chanted from the version given in the Codex Calixtinus. Neither Ordinary nor Extraordinary Form of the Roman Rite, but rather from the Mozarabic Rite.

Note: an earlier version of this story erroneously stated that a diocesan patronal solemnity trumps a Sunday in Ordinary Time (see below). I apologize for the error.
