One of my favorite moments, especially musically, from 'The Lord Of The Rings' is in the third film 'The Return Of The King' when Pippin lights the beacon to send for aid. The beautiful music composed by Howard Shore for this moment as the beacons are lit is literally stunning. Everytime I see the scene or even just hear the music I get goosebumps. Not kidding.
Here is a live performance, featuring Howard Shore conducting, doing the piece of music. Let the goosebumps begin.
I wanted to include the clip from the film but couldn't find one. At least one that did not have embedding disabled. No luck. So here is a link to a YouTube file of the scene.
