Cave In, the Music, Kings Of Leon, the Distillers, and "Jackass" principal Steve-O have signed on to perform as part of the Lollapalooza tour's second stage. Other acts include Rooney, the Mooney Suzuki, Burning Brides, Pharoahe Monch, 30 Seconds To Mars, and Bellydance Superstars, as well as a different local opening act in each market. As previously reported, Lollapalooza will be headlined by Jane's Addiction and kicks off July 3 in Grand Rapids, Mich.

"It's almost like how Lollapalooza was in the first year with little known acts, up-and-comers, and underground or cult classics," Jane's frontman/festival organizer Perry Farrell tells Billboard.com. "These days, things move so fast that it's hard to retain a cult status, if you will. You quickly become a legend in the music industry today. They don't take that long to develop the artists so they're a lot fresher coming to that stage. That's what we were looking for -- a lot of the fresher acts and up-and-comers."

Farrell says fans should look forward to various interactive elements at each venue, turning the experience into a pseudo-reality show. "It could quite easily start with you getting a call on your cell phone asking you to do something," he reveals. "You might have to scream for your mother, and you'll have half a code. The other half of the code will say, look for someone who is calling for their mommy. Those two codes connect and those two people will then be told where to go to collect a prize, or go for something even bigger or grander by doing something for the entire audience."

Lollapalooza also features Audioslave, Queens Of The Stone Age, Incubus, Jurassic 5, the Donnas, and on select dates, A Perfect Circle. Farrell says that after years of resistance, he is mulling releasing both a live CD and DVD document of this year's festival. "Kids want quality products, and now we have new products to be made that we didn't have in 1991," he says.
