There are a few places on YouTube where you can listen to the soundtrack to The Talos Principle, as well as being available on Spotify. However, there is one piece of music that I can't find anywhere: the theme played when you stand in the doorway to eternity in World C, that carries through when you actually step into it. It is also played when you reach 'heaven' after ascending the tower. The piece of music can be heard in this clip from 0:13 to 0:52, anyone who has played through the game will be familiar with it.
I've trawled through the soundtrack and it isn't anywhere; is it an outside piece of music? Can anyone help me identify the name of this track?
