Big Boi has been added to the bill for Southern California's Epicenter TwentyTen festival this September. The Outkast member, who recently released his latest solo effort 'Sir Lucious Left Foot: The Son of Chico Dusty,' has been making the rounds promoting the album, his first with his new label home, Def Jam Records. The long-delayed effort also featured production from Big Boi's fellow Outkast member, Andre 3000.

The festival, now in its second year, will feature the likes of several artists who will be making special appearances solely for the event. The festival will be Blink-182's only concert performance for the year, Bush's first show in nine years, and the sole California concert stop scheduled for 2010 for both Kiss and Eminem.

Located just 35-minutes from downtown Los Angeles, the multi-stage event will be held over two days at the Auto Speedway in Fontana, Calif. tickets for the event are on sale now, and start at $75, VIP passes and two-day package deals are also available.
