After a week of building anticipation and dropping hints via social media, Kellogg's Pop-Tarts has finally revealed the location for the first of two "pop up" concerts as part of the Crazy Good Summer campaign.

Drumroll, please ...

On July 19, Chicago will welcome headliners Boys Like Girls, Carly Rae Jepsen and Austin Mahone at Charter One Pavilion at Northerly Island.

If being chosen as the host city out of thousands of others across the country wasn't good enough, Chicagoans also will be happy to know that they will be seeing some of the summer’s hottest acts absolutely free of charge.

Visit the Pop-Tarts' Facebook page to find out how you can RSVP for a chance to claim free concert tickets. Be one of the first 4,000 fans to register and receive a code redeemable for two free tickets to the show.

A second surprise concert in a different undisclosed city will be taking place later this summer along with ongoing sweepstakes from Pop-Tarts Crazy Good Summer in partnership with Live Nation.
