So I was watching videos off atv.dhs.org, and watched the preview for Hill-Jacks 3. And they played this song and I've heard it numerous times on TV commericals, movies, etc. So if anyone knows what song this is, let me know.

Hill-Jacks 3 Preview

 

I remember it from the movie Excalibur, I think it was also in the soundtrack/score for End of days....

 

Just email the originators of the clip. They have to know the name and give credit to the original author in the video, so he should know.
