Shacknews reports that "I am Murloc," a trash-metal track played by Blizzard's own band, Level 70 Tauren Chieftain, will be available as a free download to PS3 and Xbox 360 Guitar Hero 3 owners starting tomorrow. "I am Murloc," a tribute to the articulate fish people from the popular World of WarCraft MMO, made its debut at the 2005 BlizzCon event.

The track's free release is considered a pre-festivity festivity which leads up to the Worldwide Invitational beginning this weekend.
