Pacific Festival: OC has just announced that our favorite "non-singer" of a producer Calvin Harris has been added to the 2011 lineup. It will be Calvin's first time performing in Orange County. The 2nd Annual event will take place on August 13, 2011 at Oak Canyon Ranch at Irvine Lake in Orange County, CA.

Some early bird tickets for both general admission and VIP are already available, so you'll want to head over to the Pacific Festival:OC's Eventbrite page for more information. 

For the rest of the lineup, have a look after the jump!
