The bass reverberates through bare feet on grass. Sweat-slicked students sway beneath the May sun, their faces turned skyward toward artists whose names command marquees worldwide. Along the shore of Lake Michigan, Northwestern’s Lakefill transforms into something unbelievable: a music festival drawing 12,000 attendees, orchestrated entirely by undergraduates, featuring chart-topping artists and professional-grade production.
Yet this polished spectacle, now a cornerstone of Northwestern identity, emerged from the most unlikely soil: anti-establishment rebellion.
“We’d had huge demonstrations against the Vietnam War, we were all taking psychedelics and smoking weed,” recalls Donald Stout (Weinberg ’73), who co-founded the festival amid Vietnam War protests. “We wanted to do something different and more homegrown. More do-it-ourselves, and not so slick and produced and commercialized.”
This paradox defines Dillo Day’s half-century evolution: an event conceived as a rejection of mainstream culture which has become one of Northwestern’s most cherished traditions. In this transformation lies a larger story about how American youth movements evolve from margins to mainstream, how rebellion becomes tradition, and how a university better known for academics than revelry became home to an unparalleled celebration of sound and spectacle.
Spring, 1973. Richard Nixon occupied the White House. The last American troops were withdrawing from Vietnam. Pink Floyd released “Dark Side of the Moon.” And two Texans at Northwestern University decided their campus needed something radical.
Donald Stout and George Krause — Houston natives transplanted to Evanston’s manicured shores — found themselves alienated by Northwestern’s social landscape. Greek life dominated the social calendar, even hosting an annual “Spring Thing” featuring mainstream performers in carefully managed settings. For students immersed in the counterculture — the anti-war movement, experimental art, and yes, psychedelics — these options felt sterile.
“At that time, there was kind of a big divide between that set and, what I would say, the rest of us,” Stout explained.
Returning from spring break, the pair brought back more than just tans. An Elizabethan fair at Rice University had planted a seed. They established Armadillo Productions, an homage to Austin’s legendary Armadillo World Headquarters, where progressive country, rock and blues artists created a cultural phenomenon in their home state.
“I was the dreamer and he was the doer,” Krause said, describing their partnership.
Their vision materialized through handwritten posters advertising “The First Annual ‘I Don’t Think We’re in Kansas Anymore’ Festival and Fair” on the Lakefill. The Wizard of Oz reference wasn’t subtle — this would be a conscious departure from Northwestern’s established reality.
“It was like, ‘Where are we? This is really different. This is special. This is not ordinary,’” Stout recalled.
The inaugural festival embodied spontaneity. Three local bands performed alongside unscheduled acts like “Joe the Bagpipe Player,” who commandeered the stage without invitation or objection. Carnival games, dunk tanks, and even a Lord and Lady Godiva contest — where participants disrobed for audience approval — created an atmosphere of uninhibited celebration.
Perhaps most remarkably, in an era before university liability concerns dominated event planning, kegs of beer materialized on the Lakefill. “I have no idea how we accomplished this,” Stout admitted. “Some of us were 21, but there were lots of people there who were not. I don’t remember how we pulled that off, but we did.”
Northwestern’s administration, typically strict about campus activities, displayed uncharacteristic permissiveness. “The university turned a blind eye, or at least was tolerant,” Krause noted — a response unimaginable today.
Dillo Day wasn’t Northwestern’s first attempt at springtime revelry. Aged flaxen boxes full of archival photographs evidence the excitement May has brought for Northwestern students, with spring festivals dating back decades. Before Dillo existed, the Greek life-sponsored event “Spring Thing” with musical performances was the leading end-of-year festivity, alongside formal dances, May Sing and May Week.
What distinguished Dillo was its persistence. While events like Spring Thing, May Sing and May Week eventually receded into archival obscurity, Dillo endured, evolving from a gathering of a few hundred organized by 20 idealistic undergraduates into the behemoth festival it is today.
The secret to this longevity may lie in Dillo’s psychological function. Archived promotional materials consistently emphasize the festival as an escape valve for Northwestern’s pressure-cooker academic environment — a university where winter seems eternal and library carrels become second homes.
“There’s all this pent up energy,” Richardson explains, leafing through decades of posters promising liberation. “There’s a lot of discussion about that in the documents, about people getting out of the library, for instance, and going and being un-Northwestern-like for a day.”
This yearly permission to shed academic identities — to become, if only briefly, something other than ambitious strivers — created a tradition that resonated across generations of students despite radical changes in American youth culture.
In 1980s Evanston, Bill Figel (Medill MA ’86) and his classmates would never have imagined their college town hosting a music festival that would one day attract chart-topping artists. This was a city still clinging to its temperance-era identity, where securing a liquor license remained nearly impossible, and Northwestern’s reputation centered on academic intensity rather than cultural vibrancy.
“Evanston being dry, I think a lot of people thought it wasn’t really the party that Wrigleyville was,” Figel recalled. “You didn’t think of Evanston as a place to go and enjoy a beer and listen to a concert and jump around and dance.”
Yet beneath this buttoned-up exterior, Northwestern’s musical heartbeat was strengthening. Historic venue Biddy Mulligan’s in neighboring Rogers Park began hosting “Northwestern Night” on Thursdays, creating a crucial pipeline between campus talent and Chicago’s thriving music scene.
“On Friday, Saturday and Sunday, they would have really top acts,” Figel says. “Chuck Berry would be in there, or John Lee Hooker, and then just a parade of traditional blues bands. But for them, Northwestern students meant that they were drawing a new crowd. They were also bringing in the new sounds.”
This incubation of musical talent occurred at the precise moment when Dillo Day was finding its footing as an annual tradition. What began with three local bands and a rogue bagpiper gradually expanded its musical ambitions, tracking alongside shifts in American popular music — from folk and psychedelic rock to hip-hop, electronic dance music and beyond.
University Archivist Matthew Richardson sees Northwestern’s unique academic ecosystem as perfect soil for a world-class festival. “You get people who are into music, but also people who tend to be very driven and ambitious and want to put things together,” he explained. The presence of Bienen School of Music and School of Communication, combined with Kellogg’s business acumen and proximity to Chicago’s music industry, created an environment where artistic vision met organizational talent.
By the early 2000s, Dillo had transcended its humble origins. Instead of student bands playing background music for carnival games, performances became the festival’s centerpiece. The event began attracting recognizable names — artists like Grammy winner Kendrick Lamar, Chicago native Chance the Rapper, electronic act MGMT and performers who would later become industry leaders.
Recent years have brought performances by Swae Lee, Dominic Fike, and other artists whose streaming numbers reach into the hundreds of millions. When A$AP Ferg performed in 2019, students packed the Lakefill so densely that the crowd became visible from buildings across campus, a sea of bodies moving in unison to bass drops that reverberated across the lake.
This transformation isn’t merely about booking bigger names. It represents a fundamental shift in the festival’s purpose — from a day of countercultural gathering to a professional music experience that rivals commercial festivals in production quality while maintaining its uniquely undergraduate character.
These days, student-run group Mayfest Productions focuses on bringing major global artists to the Lakefill rather than asking alternative bands to play in the background. This is SESP fourth-year Alex Kahn’s second year as co-chair, and she has no desire to hit the brakes on Dillo’s ascent.
“We pride ourselves on making a true music festival,” Khan says. “It’s not just another student concert. We’re trying to get bigger and better every year.”
The scale of this ambition becomes apparent when examining Mayfest’s organizational structure: 17 executive board members overseeing 10 specialized committees, each responsible for a different facet of the festival — from talent booking to security coordination, from vendor management to sustainability initiatives.
This machine never truly powers down. As soon as the final notes fade from one Dillo Day, planning begins for the next. Summer months become dedicated to budgeting and artist booking, with recruitment occurring upon return to campus in fall. The process of selecting committee members involves multiple rounds of interviews, with hundreds of applicants vying for coveted positions.
“Every year we’re getting closer and closer to really building out this huge professional festival with top level talent,” Khan says. “Every year we’re consistently bringing a built out lineup that has high level acts at every single slot.”
Negotiations with agents for top-tier performers require business acumen that belies the organizers’ undergraduate status. Contracts specifying everything from stage dimensions to green room requirements must be meticulously honored. Security plans undergo scrutiny from university police and fire departments. Even portable toilet placement requires careful strategy.
Medill first-year Celeste Eckstein, who serves on Mayfest’s Production committee, found herself immersed in logistics that most students never consider. “It’s something that’s so different from my other academic interests and the other organizations that I’m a part of,” she said. “It’s really cool to have some variety in my extracurriculars and get to do things that are just fun and interesting to me.”
Despite this professional approach, Mayfest maintains an almost fanatical commitment to student autonomy. “It’s been entirely student-run from the beginning and will forever be that way,” Kahn declared. “We truly are the most hands-on in every single aspect.”
This independence extends to Mayfest’s organizational culture. Members sign NDAs to prevent leaks about artists and themes, creating an atmosphere of shared secrecy that strengthens internal bonds. “The more you get involved in what we do and the community, the more you buy into what we’re doing,” Kahn explained. “You feel protective because everyone works so hard on all these individual parts all year, and you want them to get to announce it the way that we want to.”
The contrast with Dillo’s early days couldn’t be starker. Where Stout and Krause once recruited volunteers through personal connections, today’s Mayfest conducts formal interviews. Where founding members once slept on the Lakefill to protect equipment, today’s festival employs professional security firms. Yet in this professionalization lies not betrayal but evolution — students maintaining control of their celebration while developing skills that rival industry professionals.
On the morning of Dillo Day, Northwestern undergoes a sartorial transformation. Students emerge from dormitories and apartments in coordinated outfits, their Instagram feeds soon flooded with photographs documenting their interpretation of that year’s theme.
This aesthetic coordination represents a stark evolution from Dillo’s countercultural origins. Archival photographs from early festivals capture students in what Stout describes as the “hippie era” uniform—bell-bottom jeans, tie-dyed shirts, long hair and beards. These weren’t costumes but identities, visual manifestations of political and social positioning.
After months of speculation, on Feb. 17 Mayfest announced that this year’s theme would be Carnival, hailing iconography of fair festivities and the predominant colors of red and white. Mayfest coordinated themed dining hall menus for the announcement, and also teamed up with the student fashion magazine Stitch to make outfit inspiration boards.
“We didn’t think of it as costuming at that time, but in a sense, it was a way of identifying ourselves with the new cultural phenomenon,” Stout says.
More pointed political statements appeared throughout the festival’s early years. One archived photograph shows a student wearing a shirt declaring “Rally Against the Draft” — fashion as protest, clothing as manifesto.
“It was a time when it seemed like there was great change happening,” Stout explained. “We were both hopeful and also, you know, the Vietnam War had not ended yet, which was a huge disappointment. But there was hope that society was changing and that things were becoming more open and freer.”
The first Dillo Day to be themed was 2019, and the concept was “Retro.” Eckstein says themes make each festival “distinguishable” and “memorable” because students can recall each year by one style –– khaki shorts and rucksacks for Camp, neon and metallic accents for Planet Dillo, leather tassels and boots for Return of the Rodeo.
The process of selecting these themes involves careful consideration. Kahn explains that Mayfest needs a concept broad enough to accommodate individual creativity while specific enough to create visual coherence.
“People are going in a lot of different directions, which is why I think this one is kind of fun,” Kahn said of the Carnival theme. “There’s not a right or wrong way to do it.”
Medill first-year Celeste Eckstein sees the themes as fulfilling dual purposes — creating communal experience while preserving personal expression. “A theme is fun because it still gives people a lot of room to be creative and expressive, but it also creates a unifying atmosphere,” she observed.
Kahn connects Dillo’s approach to broader trends in concert culture, noting how fans of artists like Taylor Swift and Harry Styles arrive at performances in elaborately coordinated outfits. “You see this happening in these big concerts as well, where people really want to dress in theme,” she said.
This evolution — from spontaneous expression to coordinated themes — mirrors larger shifts in American youth culture. Where Baby Boomers used fashion to reject mainstream values, today’s students embrace the curatorial aspect of identity, crafting aesthetics that simultaneously signal individuality and group belonging.
Yet beneath the Instagram-ready outfits lies a continuity of purpose. Whether through political slogans or carnival costumes, Dillo Day has always offered Northwestern students the opportunity to temporarily shed their academic identities and embody something more playful, more expressive, more free.
