The 4-day festival also included headline sets by Iron Maiden (Jun 5), Kings Of Leon (Jun 6) and Metallica (Jun 8). On June 17, Linkin Park will release their new album, "The Hunting Party."

The project sees guest appearances from Helmet's Page Hamilton, System Of A Down's Daron Malakian and rapper Rakim. The follow-up to 2012's "Living Things" is the first project by the band since lead singer Chester Bennington joined Stone Temple Pilots last year.
