Once again, the hard rock world will spend Memorial Day Weekend converging on Pryor, Okla. for the seventh annual Rocklahoma Festival. Earlier today, AEG Live, the promoters of the festival, announced the lineup for the three-day event. As usual, this year's roster brings together many top present and classic hard rock and metal acts from May 25-27.

Rob Zombie, Chickenfoot and Creed will headline the event, with Megadeth, Slash and Queensryche among the other big names that will perform. Other well known groups to rock Pryor's "Catch the Fever" Festival Grounds include Jackyl, Puddle Of Mudd and The Darkness. In total, 38 acts will perform on three stages over the course of the festival. Rocklahoma's website has a complete list.

"Rocklahoma has quickly become the rock 'n' roll party of Memorial Day Weekend, and 2012 is going to take the party to a whole new level," said Joe Litvag of AEG Live. "We've got a great balance of talent this year with some amazing classic artists covering the last three decades along with plenty of today's rock."
