On a whim I copied the Halo III soundtrack to my e-book reader recently and then on a coach journey started listening, and these tracks came on, and I was reminded just how good this soundtrack is; here are some examples:

Halo 3 OST - {Tsavo Highway} To Kill A Demon - YouTube

Halo 3 OST - {The Storm} This is The Hour - YouTube

Halo 3 OST - One Final Effort {Extended Version} - YouTube

Halo 3 OST - {The Ark} Behold a Pale Horse - YouTube

I remember the first time I heard ‘This is The Hour’, and I thought to myself ‘this is it. This piece of music is everything I want to be’. Xyrael’s theme.
