BlizzCon 2011 just got even better with today’s announcement that the closing concert for this year’s show will be headlined by none other than Foo Fighters. The multi-platinum rockers will take the stage to close out the convention with a set drawn from the many iconic anthems of their 16-year career. We also announced today that The Artist Formerly Known as Level 80 Elite Tauren Chieftain, Blizzard’s in-house metal band, will be returning to BlizzCon this year and will open for Foo Fighters. Tickets to the convention are currently sold out, but the BlizzCon Virtual Ticket, which offers multi-channel Internet streaming worldwide, is still available. Check out the official announcement for more information.
