What might be this year's baddest bad-ass biker event, the five day Rock 'N Rev 2010 festival in Sturgis, S.D. is now badder and more rockin'. Organizers have announced that Guns N' Roses will headline the final night of the festival, which already features a dangerously amped-up lineup, including Godsmack, Alice in Chains, Hellyeah, 3 Doors Down, Daughtry, Stone Temple Pilots, Wolfmother, Hinder, Creed and Three Doors Down. If they show up for the concert, it will mark Guns N' Roses sole U.S. appearance in 2010

Rock 'N Rev will take place in from Aug. 9 to 13 and tickets are $45 per day, with five day passes going for $150 and up. The festival will take place at the newly constructed Rock N' Rev amphitheater at Monkey Rock, USA, which will boast 12 bars and thousands of drunk bikers.

"We are truly blessed to be able to announce the addition of Guns N' Roses at this historic moment in the band's history," said Daniel E. Catullo III, event partner DC3 Music Group's co-founder. "Monkey Rock's vision to create a nationally recognized brand among the world's top motorcycle rallies is a perfect fit for us, and we couldn't be more excited to welcome them as our partners."
