Heading to BlizzCon this year? Then you are in for something special, especially if you are a fan of Jack Black and Kyle Gass. The members of Tenacious D will be in full effect at this year's BlizzCon rocking the house in a finale of the two day event. Their unique narrative rock style and eccentric playlist should play host to an amazing time at the WoW, StarCraft, and Warcraft community meetup of epic proportions. This event is shaping up to be a must-see for Blizzard fans and if you are anywhere near a fan of Blizzard it will have you intrigued. The event will take place live as well as over the internet and through DirecTV, but it will cost you. Tenacious D will perform October 23 at the BlizzCon 'Closing Ceremony', be there or be square!
