causes of siatic nerve pain

Does anyone know where to find this song in pure audio format (i.e. Mp3)?



Iapos;ve only been able to find shorter versions (between 2-3 min. Long on the Requiem for a Dream soundtrack) which makes me sad because I love this song I know it has been used it in countless movie trailers/commercials but I still think it is great. Iapos;m not even sure if the song playing in the above youtube clip is the "official" version.
