The annual rite of summer passage, Wisconsin's Rock Fest, is back for its 20th anniversary year and this time around fans will be treated to headlining sets from Korn, Motley Crue and Kiss.

Officials revealed most of the lineup Monday morning (Feb. 18), with one mystery headliner yet to be named, but the four-day festival should provide a great mixture of rock's most-respected vets and the new guard of in-demand hard rock acts.

According to the Leader Telegram, the mystery headliner will head up the opening night bill on July 18, with support from Seether, Halestorm, All That Remains and Aranda. Korn front the bill on July 19, with the Offspring, Theory of a Deadman, Pop Evil and In This Moment also taking part.

The Saturday July 20 bill is headlined by Kiss, with support from Megadeth, Stone Sour, Hellyeah and Warrant. The final night (Sunday, July 21) has Motley Crue finishing out the music weekend, preceded by Whitesnake, Skillet, Device and Otherwise.

Rock Fest runs July 18-21 at The Venue in Cadott, Wis. Tickets for the event will go on sale Feb. 23 at the festival's website here.
