Blizzcon with a big concert. Two years ago it was Ozzy Osbourne, and Tenacious D followed -- this year it'll be the Foo Fighters' chance for post-gaming convention immortality.
Blizzcon takes place at the Anaheim Convention Center on October 21 and 22. If you were unable to score yourself a ticket, Blizzard is offering a pass to take part in the festivities virtually for $39.99, either via the internet or through DirecTV.
