Instrumental music: 'Epic sounding'

Hi guys, great forum you got here.

What I am after is similar music to the ones listed below, I can't find any similar ones. Also it'd be nice for decent lenght ones (longer than 3 min)

Format:
Artist - Song

Similar to this:
Clint Mansell - Two Towers Song
Halo 2 - Theme Song Mjolnir Mix

These also, but the above two are somewhat more 'epic'.
Matrix - Matrix Classial Techno Remix
Metallica - Orion
Paul Oakenfold - Gamemaster

Instrumental and techno music that "pumps you up", so to speak. Instrumentals/techno with an epic sound to it, such as the Halo 2 Theme Song for example or Two Towers. Sorry I am terrible at explaining this.

So, what can you guys suggest to me!

'Also Sprach Zarathustra' by Richard Strauss
- you might know it as 'theme to 2001: A Space Odyssy' or 'Ric Flair's Music'

anything from The Omen

Tubular Bells by Mike Oldfield
- Theme from The Exorcist

anything by Front Line Assembly
they are a proper industrial band but they did the soundtrack to Quake 3: Arena

anything by Rammstein

How about music by Steve Jablonsky? I don't know how "epic" it is but I think you'd like it. My favorite of his is titled "My Name is Lincoln". Anything of his from The Island movie soundtrack as well as most of his other music. By the way, welcome to the forum.

Anything by John Williams (Star Wars, Close Encounters, ET...)
