The Warped Tour returns to the First Midwest Bank Amphitheatre (I-80 and Harlem in Tinley Park) on Sat 7/31 with a full-to-bursting bill of punk rock, hardcore, emo, crunkcore, ska, metalcore, and more. Of the more than 70 bands spread across the festival's seven stages, several have been around the block a few times, including local heroes Alkaline Trio, California pop-punk troopers Face to Face, "up the punx" loyalists the Casualties, ska punks Reel Big Fish, and mid-90s skate-punk mainstays Pennywise. On the heavier side, the festival's bookings include the Dillinger Escape Plan, Every Time I Die, Iwrestledabearonce, and Andrew W.K. The emo bands on the bill can usually be recognized by their cutesy names (the Rocket Summer, Automatic Loveletter, Hey Monday) even before you see their clever haircuts. Set order is determined the day of the show; gates open at 11 AM and music starts at noon. Admission is $40, $34.25 in advance through livenation.com.
