The three-day festival takes place Friday through Sunday at Humboldt Park and features headliners The Replacements, The Pixies, Blink 182 and Fall Out Boy.
Fest-goers will not be able to bring their own food or drinks but both will be available for purchase inside, including vegetarian and vegan options.
