It's going to be a great weekend of rock this July as the fourth headliner for the 20th anniversary of Cadott, Wisconsin's Rock Fest has been revealed. It's none other than Three Days Grace, who will kick off the long weekend by headlining the Thursday, July 18 bill.

They'll be joined on Thursday (July 18) by Seether, Halestorm, All That Remains and Aranda. As was previously reported, the other three nights are being headlined by Korn (July 19), Kiss (July 20) and Motley Crue (July 21).

In addition to the top-billed acts, the music weekend will include sets from the Offspring, Megadeth, Whitesnake, Theory of a Deadman, Stone Sour, Skillet, Pop Evil, Hellyeah, Device, Nonpoint, Warrant, Otherwise and several others.

Three Days Grace have been out on the road in support of their 2012 album 'Transit of Venus.' Following the departure of frontman Adam Gontier earlier this year, vocal duties have been taken over by My Darkest Days singer Matt Walst.

The full lineup and ticketing information can be found at the Rock Fest website here. In addition, the Rock Fest 2013 free Mobile app has just been released and is available now in App stores.
