The Latin Mass Society was due, as for many years past, to employ professional musicians to accompany not only the 'major' services of Holy Week but also Tenebrae in St Mary Moorfields, London. Since these celebrations cannot now take place, the musicians have recorded some pieces from their own homes and edited them together.
The group is Cantus Magnus, under the direction of Matthew Schellhorn.
These are being released primarily from the LMS Facebook page. Here is a Vimeo version of the first one, a piece from the Tenebrae of Maundy Thursday set by Anerio.
