“Requiem for a Tower” is actually a version of the track "Lux Aeterna" which is the theme song, leitmotif and the penultimate piece in the “Requiem for a Dream” score. The “Requiem for a Tower” version of the track was re-orchestrated with a choir and full orchestra for the “The Lord of The Rings: The Two Towers” trailer. The "Requiem for a Tower" was made exclusively for the trailer and was not featured in either “Requiem for a Dream” or the “The Lord of the Rings” film trilogy. It was arranged by Simone Benyacar, Dan Nielsen, and Veigar Margeirsson. Although never intended for release, after considerable demand by fans this piece was made available on the iTunes Store in October 2006, as part of the “Requiem for a Tower” album release from Corner Stone Cues.
