I don’t think the old videos are all up yet. It was called “Evocation of the Sun Demon Sorath Live Ritual”.
You can get videos discussing it on you tube,and we just got a new post from someone who is posting older videos with permission.
I don’t see the Sorath video up yet. There is a mirror copy here: all credits given and belong to BALG and I have an offer out to @AnthonyS (as well as Timothy) to get my copies as well.
