We all know the ancient story of the greatest band of all time, Tenacious D.

Young Jables ranaway from his home in Kickapoo searching for the secrets of rock and finds finger heavy guitar player Cage. After figuring about the legend of The Pick of Destiny, they both go on an adventure to find the pick that will change their life and music.

After breaking up they find each other again to fight the Devil to save Cage and ultimately save the planet through there kick ass music.

The song that changed my life is the battle that Tenacious D and the Devil had on a dark and cold night.

(BTW the devil is David Grohl, so that's pretty bitchin')

NSFW SONG.
