"After last year's success at Discovery Park, the commitment from Mike Testa of Sacramento Convention & Visitors Bureau and the city, we believe Sacramento is a great home to build a multi-day destination music festival. I am excited to bring the biggest rock show in the past few years to the region," says festival creator/producer Danny Wimmer of Danny Wimmer Presents.

"The economic impact tied to festivals of this magnitude is significant," said Mike Testa, senior vice president for the Sacramento Convention & Visitors Bureau. "For this year's two-day event, when consumed hotel rooms and visitor spending and local attendance are factored in, we expect the economic impact to be the equivalent of a city-wide convention for Sacramento. That number is in the millions financially."

Discovery Park is a 160-acre park conveniently located near downtown Sacramento, where the American and Sacramento Rivers meet. The Discovery Park boat launch allows boaters access to both the American and Sacramento Rivers,and the park features bike trials, picnic areas, and a playground.
