Freaky Deaky

React Presents' annual EDM-centric Halloween party returns to Toyota Park, armed with a lineup of electronic acts and hip-hop artists. This year, headliners include Disclosure (turning in a DJ set), DJ Snake, Tiësto, Schoolboy Q and DJ Khaled. The undercard is just as strong, including house music producer Duke Dumont and "Panda" emcee Desiigner. Attendees are encouraged to come in costume and enjoy three stages of music, carnival rides, haunted attractions and more spooky stuff.
