I have a large number of great videos to post so please bear with me. Here is an awesome video of Tenebrae at the Dominican House of Studies. It's only three minutes long. It isn't of the entire service, but fr those who have never attended Tenebrae, it will give an idea of what the service is like. If nothing else, it is worth watching simply for the Gregorian chant however, I am dissapointed that the strepitus was not included in the video.
