On a Thursday evening at Celtic Grooves, a studio tucked into a converted warehouse on Mill Street, fifteen dancers line up for what the schedule calls "Irish Fusion Level III." The first thirty minutes look familiar enough: hard shoes striking the floor in rapid-fire trebles, bodies held rigid from the waist up. Then the instructor, Marco Reyes, switches the music from a traditional reel to a chopped and remixed track with a trap beat. The arms come unstuck. Hip isolations follow. By the end of the hour, one student is threading a jazz square through a sidewalk step, arms slicing through positions borrowed from contemporary.
This is not your grandmother's feis. In Rock Valley City, a community of roughly 180,000 about forty miles west of Chicago, Irish dance is being rebuilt for bodies and audiences that did not grow up with it.
TheStudios Driving the Shift
Celtic Grooves and its rival-turned-collaborator Step into the Future have become the twin engines of this movement. Both opened within two years of each other—Celtic Grooves in 2016, Step into the Future in 2018—and both were founded by dancers who trained in traditional Irish forms before migrating into commercial and concert dance.
Reyes, 34, started competing at the regional level in Milwaukee at age nine. By his twenties, he was dancing backup for pop acts in Los Angeles. When he returned to the Midwest and opened Celtic Grooves, he did not advertise it as an Irish dance studio. "I called it a movement space," he says. "People walked in for hip-hop, found out I had TCRG certification, and started asking if we could combine them. I didn't plan the fusion. The students demanded it."
At Step into the Future, co-founder Aisha Okonkwo took a different path. A Nigerian-American dancer who trained in ballet and West African forms before picking up Irish dance as an adult, Okonkwo was drawn to the rhythmic precision of hard shoe. "It felt related to sabar, to tap, to anything where the feet do the talking," she says. Her studio now runs a "Global Rhythm" track that pairs Irish step with Guinean djembe and house music.
Enrollment at both studios has climbed steadily. Celtic Grooves reported 220 students in its 2023–2024 season, up from 87 in its first year. Step into the Future now serves roughly 180 dancers across programs, with its Irish crossover classes consistently waitlisted.
What the Fusion Actually Looks Like
The Emerald Ensemble, a pre-professional troupe drawn from both studios, offers the clearest answer. Their spring show, Crossings, ran for three nights in April at the Rock Valley City Arts Center. One piece, "Hard Shoe House," set championship-style footwork against a 120-BPM Chicago house track. The costumes split the difference: stiff velvet vests on top, streetwear cargo pants below. Another piece, "Suspended Reel," featured two aerial silks routines choreographed so that the dancers' rope climbs matched the ascending phrases of an Uilleann pipe recording.
The audience on opening night was notably young—roughly half appeared to be under thirty, an unusual demographic for Irish-themed programming in a city where the traditional St. Patrick's Day ceili still draws primarily retirees.
Liam Brennan, 22, danced in "Hard Shoe House" and grew up in a family that sent five siblings to competitive feiseanna. "I stopped competing at sixteen because it felt like a museum piece," he says. "The technique was incredible, but there was nowhere to go with it unless you wanted to teach exactly what you'd been taught. This feels like I'm using the vocabulary instead of just preserving it."
Not Everyone Is Dancing Along
The expansion has not happened without tension. Fiona O'Donnell, a TCRG-certified teacher at the Rock Valley Academy of Irish Dance, has watched the fusion trend with measured concern. Her academy, founded in 1989, adheres to An Coimisiún Le Rinci Gaelacha syllabus and sends students to national and world championships.
"There's a difference between innovation and erosion," O'Donnell says. "Irish dance technique is specific for a reason. The turn-out, the lift, the placement of the arms—change those too freely and you're no longer doing Irish dance. You're doing something else with Irish dance. That's fine, but call it what it is."
She points to injury risk as a practical worry. Irish dancers train for years to stabilize the upper body; releasing the arms without retraining the core can strain the lower back. "I've had transfer students come to me with habits that take months to undo if they want to compete," she says.
The rivalry is professional, not personal. O'Donnell admits she has sent students to Emerald Ensemble performances when they need choreography
