Blizzard just announced that the Foo Fighters will be headlining BlizzCon 2011's closing concert! As usual, The Artist Formerly Known as Level 80 Elite Tauren Chieftain will be opening for the main act. If you're not familiar with TAFKAL80ETC, it's a band comprised of Blizzard employees, including president and a co-founder Mike Morhaime on bass and Art Director Sam Didier on vocals.
If you'd like to watch the concert from home, you can pick up a BlizzCon Virtual Ticket. Previous BlizzCon headliners include Tenacious D and Ozzy Osbourne.
Also, don't forget that Wowhead is co-hosting a BlizzCon party with WoW Insider on Thursday, October 20 starting at 5 p.m. PDT! If you're in the area for BlizzCon, stop by the Tangerine Grill & Patio at the Anabella hotel. If you're not, you can watch the whole thing live on GameBreaker.TV!
