Watch out, it's Godsmack! And they're coming to Rockfest 2012.

Def Leppard and Iron Maiden are two of the top performers that will be headlining this year’s Rockfest this July in Cadott. Fans of Maiden will be able to see them perform on Saturday, and Def Leppard fans (who’ve patiently waited a year to see them) will get their fix on Sunday. Friday’s slate includes Five Finger Death Punch followed by the heavy metal headliner Godsmack. Thursday’s headliner has yet to be announced, but Buckcherry has the on deck slot. Acts preceding Maiden on Saturday include well-known rockers Papa Roach and the one and only Alice Cooper. 80s rock fans will be pleased to see Poison on the docket on Sunday, prior to Leppard. Other acts scheduled to preform will include Hollywood Undead, Adelitas Way, Cydonia, and many more.
