If blues music is considered Chicago’s heart, house music is its pulse.

ARC Music Festival, now in its sixth year, is one of the city’s largest immersive concentrations of house music. This year it expands to four days, running Sept. 4-7 in Union Park on the heels of the city’s House Music Festival and Conference, which is presented by the Department of Cultural Affairs and Special Events this weekend in Millennium Park. ARC is also hosting some 35 afterparties across the city Labor Day Weekend as part of its ARC After Dark series, in addition to sets at Castaways Beach Club under the “ARC at the Lake” umbrella, and an evening cruise from DuSable Harbor.

Becoming a destination festival in less than a decade is what organizers see as proof of the genre’s influence.

“People treat it like a pilgrimage to the home of house music,” festival founder John Curley said in a recent phone interview. “There are so many artists that want to play, and we’re not a massive festival, we’re only four stages. Trying to accommodate these exciting new artists is really tricky, so that was a factor, but we always want it to feel very much Chicago-centric. The concentration of Chicago-heads is always exciting.”

Growing up in Evanston, Curley’s introduction to house music’s local roots came from the late Dave “Medusa” Shelton, owner of the bygone Lakeview club Medusa’s, who gave him his first DJ residency. Regaling a young Curley with tales of house music pioneer Frankie Knuckles and unabashed queer spaces, Curley still credits Shelton for connecting him with a culture he was then too young to experience firsthand.

He founded Auris Presents in 2020 alongside Nick Karounos (former partner in React Presents, which produced Spring Awakening until 2021), Joe Quade and Stuart Hackley (who is no longer involved). The company’s venues, including Radius, Concord Music Hall and Prysm, only hosted a handful of shows before the COVID-19 pandemic halted business. Plans for ARC took shape during the off time, and by 2021 its first installation filled a void in the city’s festival landscape after the EDM festival North Coast made the move to the suburban Bridgeview later that year.

Many first-year artists, including Derrick Carter, Honey Dijon, Green Velvet (aka Cajmere aka Curtis Jones), and DJs Heather and Lady D (performing this year with Colette and Dayhota as SuperJane, 2 p.m. Sept. 5 on Area909 stage), return this year, keeping the programming ingrained in Black, queer Chicago dance culture.

New to this year’s event is The Midway stage. Named to honor spaces like Midway Plaisance (home to several public dance events like Radio WAAH House Music Summer Beatdown) and Frank Lloyd Wright’s short-lived Midway Gardens, its main inspiration draws from Midway Airport, according to Curley, highlighting those artists keeping the tradition and reimagining it through a worldwide lens in 2026.

“The growth feels limitless,” says DJ Heather, who has played every year. Comparing ARC to Detroit’s Movement Fest, Ultra in Miami and Sonar in Barcelona, she adds, “Having it in our own backyard is special. There are so many people who have contributed to this movement, and it’s up to us to evolve and keep the legacy alive.”

While Lollapalooza, the aforementioned North Coast and even Lyrical Lemonade’s Summer Smash have all created space for techno and EDM artists on their stages over the years, ARC hopes its more intentional connections between history, location and sonic sprawl set its experience apart. In some ways, Curley sees these values reflected in the average age of attendees at ARC, skewing more toward fans in their thirties and older, whereas Lolla, North Coast and Summer Smash garner much younger crowds.

“We don’t want to gate-keep it,” Curley jokes. “But the way we book it, I think, appeals to a more mature or less typical audience. We encourage everyone to come, but we know it’s not for everybody. It’s important we continue to open minds and get people here to introduce them to these artists, to new artists, and maintain some semblance of a broad reach, but you’re not seeing straight-up pop music.”

For artists whose sets typically don’t start until the late night or wee hours of the morning in the club, an all-day showcase of craft building a bridge between originators like Lil’ Louis (back-to-back with The Blessed Madonna at 8:30 p.m. Sept. 5 on Area909 stage) and the next generation is critical.

Hiroko Yamamura (back-to-back with Boys Noize at 8:30 p.m. Sept. 7 on Area909 stage) has also played the festival every year, and said that Union Park’s more “intimate” festival scale makes “your favorite heroes” more accessible. “I’m personally going to be front and center for Will Clarke” (4 p.m. Sept. 6 on The Midway) and Serafina and Fumi (in a back-to-back set with Adrián Mills at 7 p.m. Sept. 7 on The Midway).

While Curley and the rest of Auris Presents are often asked if they’ll move ARC elsewhere, they say it’s not ARC if it’s not in Chicago.

“The fact that (Union Park) is just a few blocks away from the original Warehouse … even moving out to the suburbs would be an anathema to the actual ethos” of the festival, Curley says, referencing the legendary venue in the West Loop neighborhood. “We’re very reverent to the space that we’re in. It’s taken decades for people’s attitudes toward the music and just the culture, coming from queer, Black men, to change.”

Regarding the festival’s future, artists like Yamamura and DJ Lady D – who has long advocated for house music as a subcultural movement – hope there’s a commitment to dialogue around what the next steps in community collaboration look like as things continue.

“Seeing the success of a fest like this,” says DJ Lady D, “we can focus more on impact — equitably growing the industry, leveraging our history and talent to increase revenue for the local economy, especially for our BIPOC creators. The story of house music is uniquely Chicago.”
