Guys, this is absolutely worth seeing.

There's a group out there called The Lonely Mountain Band, made up of members of Fathom, a celtic rock band.  The LMB of course focuses on Lord of the Rings prose and music.

The vid here is by a burg on one of the US servers called Lunna and uses the Song of Durin by LMB, put together with imagery from the game itself.

Pretty wicked stuff.
