YouTube claims that the music in LastEscape is protected

I believe this is the track:

http://soundcloud.com/marcus-murky/apocalyptica-insect-world (no cc license. is this based on proprietary music?)

It is in the repo, but I can't find credits for authors and license:

https://github.com/lendrick/Last-Escape/tree/master/audio

Is there a place where authors and license were written down for Last Escape? I'm sure most of the licenses (CC-BY?) require mentione of what license they are under.
