Good review of
Prometheus Triumphant by DVD Verdict Review
here. A first in which someone mentions the film score:
"The 5.1 surround audio presents a rather lush soundscape for the excellent score by composer Lucien Desar."
Also:
"The second commentary is by the composer as he discusses his involvement with the project. The score is obviously a huge part of a silent film like this, but I was still surprised at how much he had to say throughout the film. "
I haven't watched the film with my commentary yet. I am kind of cringing at the prospect that I might have said something weird.
