"Mother Earth is slow to stir. But the deeper the sleep..."
I had to teach it myself but whatever: You are now not only allowed to enjoy this wonderful piece of music, but to spam it's comment section as much as you want. Hurray!
Two Steps from Hell and their creation "Moving Mountains", part of the album "Nemesis" (and not Legend), used in trailers for the movies "Jumper", "X-Men: First Class" and "Twilight - New Moon".
I will not longer give hints how to download this. In fact I ask everyone who thought about downloading it to visit www.twostepsfromhell.com, where you can buy an album containing this song now. We owe them that favour.
And I will not answer any related questions in comments or private messages anymore. Who can read has an advantage, people.
