The following Tenebrae ceremonies were all recorded at St. Gertrude the Great Church in Ohio by the recently deceased Mr. Richard Vande Ryt (on who's surviving YouTube channel you can view other Catholic ceremonies of the "unreformed" traditional Catholic Holy Week here:

[Note that Tenebrae (i.e., Matins and Lauds for Holy Thursday, Friday, Saturday)
is always anticipated, so that the Maundy Thursday Tenebrae below is to be recited Wednesday evening and so forth, beginning about 8PM (or shortly after Compline).]
