The visuals of this clip are provided by Mirada Studios, about the making of the prologue from Guillermo Del Toro’s “Pacific Rim.  Those effects are pretty impressive, though what seems to be lost amongst all that visual wizardry is the music behind the trailer, which is provided by Ramin Djawadi (pronounced Java-dee).

The track is called “Gipsy Danger,” and it’s on the ‘Pacific Rim’ soundtrack.

It’s an awesome piece of music.
