So BlizzCon has come to a close, but it sure went out with a bang! The concert held during the closing ceremony kicked off with opener Level 80 Elite Tauren Chieftain, who said they're changing their name to The Artist Formerly Known As Level 80 Elite Tauren Chieftain (or TAFKAL80ETC if you prefer) to protest the level cap being raised to 85 in Cataclysm. For those who don't know, the band is made up of Blizzard employees, including art director Sam Didier on vocals and president and co-founder Mike Morhaime on bass.

Then came the headliner, the Prince of Darkness himself, Ozzy Osbourne. He started things off with "Bark at the Moon" and performed songs like "Suicide Solution," "War Pigs" and "I Don't Know." The encore consisted of "Crazy Train" and "Paranoid" to close the set. The best part was when Yuto Miyazawa, a 9-year-old guitar prodigy, got onstage and played guitar for "Crazy Train." He met Ozzy, his rock idol, on the Ellen Degeneres Show in May after playing the song on the episode, and you can view their meeting on YouTube.
