Having leveled past their previous name -- Level 60 Elite Tauren Chieftain -- the crunching chords and pounding war drums of the newly dubbed Level 70 Elite Tauren Chieftain will once again be echoing throughout the Anaheim Convention Center's main arena at BlizzCon 2007. Exclusive to BlizzCon attendees, the concert will start at 7:30pm on Saturday, August 4, preceding the other live entertainment that evening. Get there early because seating will be first-come, first-pwned.

For those who can't wait to catch another glimpse of the band in action, we've just posted the new video for their hit song "I Am Murloc".
