After years of throwing an event at the Indianapolis 500, a new event has arisen. In the same vein as the Snake Pit, 400 Fest features an insane lineup across the board also at the Indianapolis Motor Speedway. Taking place July 21st and 22nd, this two night concert even includes camping! Friday includes Mac Miller and Cheat Codes with Major Lazer closing out the night. Saturday night features heavy hitters The Chainsmokers, Pretty Lights and DNCE opening up the night. Ticket information is available here, but thanks to the lovely folks at React Presents we’ve got a pair of 2-day passes to giveaway. Enter below for your chance to win. Gates open at 5 p.m. both nights, with performances starting at 7 p.m. See you out there!
