Established in 2007 as a classic rock destination festival with the motto “life, liberty and the pursuit of rock,” Rocklahoma was revamped in 2010 as organizers teamed with AEG Live to create an event encompassing a much broader mix of classic, current and up-and-coming rock artists.

In 2011, a record-breaking crowd of over 35,000 fans turned out for the festival, which raised over $10,000 for the American Red Cross as part of their tornado relief efforts in nearby Joplin, MO. The festival celebrates its 6th year in 2012.
