After several months of building buzz, “The Hunger Games” hits theaters today. If you’re a fan who’s been watching the trailers for months while biding your time for the film, you may be wondering about the preview’s powerful music.

The track used in the trailer (the first full-length one released for the movie) is “Deep Shadow,” written by T.T.L. (a.k.a. Through The Lens), a collaboration of new-wave Italian musician Tying Tiffany and her producer, Lorenzo Montana. Inspired by industrial and electronic music, the duo started the T.T.L. collaboration to write more music for movies and television. They also composed a track in the trailer for Ralph Fiennes’ “Coriolanus,” called “It’s Here.”
