"Man of Steel" from Fired Earth Music was used in the Percy Jackson & The Olympians: The Lightning Thief campaign.  It's a pretty epic track from the album 'Vulcano', composed by Troels Folmann, and it can be heard in the international trailer below (1:04 - end), as well as in a few featurettes.  You can watch the featurettes at Troels Folmann's blog.

Also, be sure to check out the other trailers for music by Full Tilt, Audiomachine, Two Steps From Hell, and Ars Arcana.  Yep, music from 'The Savage Tongue' is still being used in trailers.
