ARC Music Festival has just dropped its most ambitious announcement to date, revealing a massive expansion to a four-day format for 2026. Returning to its home in Union Park over Labor Day Weekend, September 4–7, 2026. Presented by Auris Presents, the festival is leaning harder than ever into its reputation as a global pilgrimage for electronic music purists.

“Every year we face the same challenge: we want to include more artists than the schedule allows. The global community is thriving, and ARC always flies by,” says ARC Co-Founder and Lead Talent Buyer John Curley. “Just as we hit our stride, the weekend is over, and we never want the music to stop. By expanding to four days, we can showcase more of the talent we love and create even more unforgettable moments for our community. This marks the beginning of a new era for ARC.”

Chicago is closing out the year with a seismic shift. Auris Presents is already a dominant force shaping the city’s modern nightlife and has announced TRANSITIONS, an ambitious new year-end festival that stretches across seven days, seven venues, and more than seventy of the most forward-thinking artists in electronic music. Running December 26 through January 1, the inaugural edition reimagines what a New Year’s celebration can look like in the Midwest, introducing a fluid, multi-venue experience unlike anything else in the United States.

ARC Music Festival has been the beacon of Chicago’s biggest celebration dedicated to house music and techno. Over the last five years, ARC has been the most successful music festival since its inception. ARC Music Festival is returning to Union Park this Labor Day Weekend from August 29 to August 31, with another impressive lineup that is too good to miss out on this year’s talent. Once again this year’s hottest genre is techno, making it go viral to the extent of headlining the Sphere, one of the biggest and iconic arenas in The States. The 2025 lineup marks its most diverse and ambitious curation yet, featuring pioneering legends, next-generation tastemakers, and groundbreaking back-to-back sets that embody the festival's spirit of innovation and celebration.
