Black Sabbath are commemorating the June 11 release of their long-awaited comeback album, 13, by participating in a live-streamed town hall event. All three members of the iconic heavy metal outfit — Ozzy Osbourne, Tony Iommi, and Geezer Butler — are participating in the program, which is being organized via Google+ Hangout. Also on board are Rage Against the Machine drummer Brad Wilk, who supplied percussion for the new record, and Ozzy’s son, Jack Osbourne, who directed several promotional clips in advance of the LP’s unveiling. Comedian Jim Norton is hosting the shindig. Watch it above and submit questions to the band via Twitter by using hashtag #AskSabbath.
