Ringer Spy Sean sends in word on a VERY small segment of music used in the trailer.
I just read your piece on the music in the second LOTR trailer and I’m pretty sure that the opening tones (when the New Line cinema logo comes on, together with the first moment of the helicopter shot over the forest) is from the opening notes of a song by Loreena McKennitt called the Mystic’s Dream.
Well, I did some research (thanks to Audiogalaxy) and it turns out Sean is right! Check out the track, and all work from McKennitt actually, I love her work. (NEW LINE: GET HER ON THAT ‘MUSIC INSPIRED BY…’ ALBUM NOW!)
