I dont care about the trailer thing, I just want to know who made that song that is playing through the whole thing.

If you have any idea just IM me.

 

Lux Aeterna ... I have it if you want me to email it to you

 

Not sure but did you read the 181 comments underneath it? Most are talking about it with such answers as:
-Clint Mansell - Requiem For A Dream.
-The song is Clint Mansell - Summer Overture
-The music isn't Summer Overture. Its based on that, but its not the same. Its a song that was created from the Requiem soundtrack and made 'more dramatic' for use in the LotR 2 Towers preview.
-The song being used here is in "BITCH I AIN'T SCARED" in the Lil' Jon album "KINGS OF KRUNK"
Took me 3 minutes to remember where it came from.
-ctually, the song is "requiem for a tower"
-It was used on The Two Towers trailer, too.
-I think it's taken from the soundtrack to "Requiem for a Dream". Check www.imdb.com to find out.
-Lux Aeterna from the 'Requiem of a dream' soundtrack. I think the tempo has been increased on this though..
-Theme from the Aronofsky film, Requiem for a Dream. It was performed by the Kronos Quartet.
