Co-executive producer of the festival for AEG Live, Joe Litvag says “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.”

Litvag goes on to say, “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. But the most unique part of this festival is definitely the campground experience…Three days and nights of craziness and chaos that only Rocklahoma can deliver!”
