However, I believe the 2006 Tech Demo was made by frictional, or at least owned by them.

I took a look at my copy of the Tech Demo - it was composed by Mikko Tarmia as well. Anyway, if you listen carefully, you will be able to hear his musical signature, typical for the whole series. Some of the tracks even survived into Overture : Anyone else noticed, that the theme from the Tech Demo's main menu is exactly the same as the one, which plays during Overture's end credits ? :-)

The one in Overture mirrors sadness over loss (Phillip's loss of his parents and a reason to carry on an ordinary everyday life). The one in Black Plague represents angst, dissilusion (about humans in general) and a loss of... sanity and clear judgement... As Philip said at the end of Overture : "From that point on, the man who once stepped into the mine, was no more..."
