"Are you ready?" Those words will likely be heard at least once at Chicago Open Air with Korn set to headline on the second night of the festival. The event is making its return to the Windy City for its second installment, bringing other headliners KISS and Ozzy Osbourne to the stage with over 40 acts in total slated to perform. Now, attendees can start mapping out their weekend as the set times have been revealed.

Doors will open at 11AM on each day (July 14, 15 and 16), allowing fans to pour into Toyota Park in Bridgeview, Ill., nice and early, affording anyone the opportunity to secure a spot along the rail to watch their favorite acts up close or grab a bite to eat from one of the various on site food vendors.

Fortunately, scheduling conflicts due to overlapping sets, a fest trait that plagues so many fans trying to cram as much rock and metal into their weekend as possible, won't be much of an issue as the set times are either butted right up against each other or separated by a few minutes. As stated, KISS will headline Friday night, with Rob Zombie playing directly before the rock icons, with other notable sets coming from Megadeth, Anthrax, Meshuggah and The Dillinger Escape Plan during the late afternoon and evening.

Monster Energy Main Stage
8:20PM Rob Zombie

Saturday's lineup leans a bit further onto the rock side than the previous day, with Korn headlining after Godsmack's set. Seether and Clutch will be two undoubted rock highlights with the metal flowing freely from Steel Panther, Body Count, Mushroomhead and more.
