Experts Only Festival 2026 is bringing John Summit’s house-and-bass takeover back to Randall’s Island Park in New York City on September 19-20, 2026. The phase one lineup puts John Summit exactly where you expect him, but the interesting part is the range around him: GRiZ, Subjohnics, Prospa, LYNY, Korolova, Taiki Nulight, Devault, Partiboi69, and a sharp undercard built for people who actually read the small names.
This is year two for Experts Only on the island, and the festival is clearly not moving like a one-off label party anymore. After a sold-out 2025 debut that drew more than 50,000 fans, the 2026 edition is expanding with multiple stages, bigger production, and a lineup that keeps one foot in club music and the other in large-scale festival chaos.

The Phase One Lineup
John Summit is the center of gravity here, both as curator and performer. That matters because Experts Only is not trying to be a neutral electronic sampler. It has a clear point of view: peak-time house, bass pressure, crossover moments, and enough left turns to keep the weekend from becoming one long main-stage loop.
GRiZ is the immediate heavyweight booking. His mix of funk, sax-led bass music, and festival-sized energy gives the lineup a different kind of lift than another straight tech-house name would. Put him on Randall’s Island after dark and the whole thing suddenly gets wider.
Then there is Subjohnics, the John Summit b2b Subtronics project that sounds ridiculous on paper and makes total sense in practice. It is the kind of booking that tells you this festival wants viral moments, not just clean programming. Summit brings the rolling house pressure, Subtronics brings the rail-shaking low end, and everyone else gets to pretend they are emotionally prepared.
Prospa add UK rave muscle to the bill, while LYNY pushes the bass side into sharper, weirder territory. Korolova brings melodic drive, Taiki Nulight keeps the UK garage and bass-house lane moving, and Devault gives the lineup a darker, more cinematic edge.
The undercard is where Experts Only starts to feel curated instead of simply stacked. Dreya V, OMRI., Partiboi69, Jackie Hollander, Dansyn, Airrica, Gabss, MADI, Soraya, Mishell, Philou, and Rohaan give the weekend a club-first backbone. That is the good version of a festival undercard: not filler, not algorithm dust, but names that make sense when the sun drops and the island starts moving.
Why Randall’s Island Works for This
Randall’s Island has a very specific reputation in New York festival culture. It feels close to the city without feeling swallowed by it. You get skyline energy, open-air scale, and that slightly surreal feeling of dancing between boroughs while the rest of New York keeps pretending it is having a normal weekend.
That setting fits Experts Only better than a sealed indoor venue would. The brand is built around release: big drops, big crowds, big hands-in-the-air records, and the kind of crowd that wants the weekend to feel like an event, not just a sequence of DJ sets. A two-day electronic festival on Randall’s Island gives Summit and crew room to make the production feel physical.
It also helps that New York has been hungry for a proper dance-focused island weekender. Pollstar reported that the 2025 debut brought more than 50,000 fans, which is not a soft launch. That is a signal. Year two is where Experts Only has to prove it can turn hype into a repeatable festival identity.
What to Watch Next
This is a phase one announcement, which means the lineup is not finished. The current poster does not split artists by day or stage yet, so the smart read is simple: treat this as the opening statement, not the final schedule. More names are expected, and the eventual day split will matter a lot for how fans plan the weekend.
The biggest scheduling question is how Experts Only handles John Summit and Subjohnics. A solo Summit set and the Summit b2b Subtronics project create two different peaks. If they land on separate nights, the festival has an obvious two-day spine. If they land closer together, expect one very loud night and a lot of people suddenly discovering the limits of their hydration strategy.
Keep an eye on stage assignments too. The lineup already points toward distinct lanes: house and tech-house, melodic and progressive sounds, bass music, UK garage, and club oddities. If the festival uses those lanes properly, the weekend could feel less like one giant playlist and more like a real electronic map.
Practical Notes for Fans
Arrive earlier than your favorite set. Randall’s Island logistics are not impossible, but they reward people who do not treat New York traffic like a personality test. Give yourself time for entry, walking, water, and stage scouting.
Plan transport before the last song. The island is accessible by public transit combinations, rideshare, and pedestrian routes, but the end-of-night rush can get messy. Decide your exit plan before the encore brain takes over.
Dress for a long outdoor day. September in New York can be beautiful, humid, breezy, or all three before dinner. Comfortable shoes matter more than the outfit photo. Tragic, but true.
Wait for the day split before buying around one artist. If you are traveling mainly for GRiZ, Subjohnics, Prospa, or LYNY, keep watching official channels until the schedule is clearer. Right now, the phase one poster confirms the artists, not the exact daily layout.
Bottom Line
Experts Only Festival 2026 is already a serious New York electronic weekend on phase one alone. John Summit gives it the brand pull, GRiZ and Subjohnics give it the festival-sized punch, and the undercard keeps the whole thing from feeling lazy.
The important part is that Experts Only is developing a shape. It is not just borrowing Randall’s Island for a weekend. It is trying to own a particular lane in New York dance music: high-volume, high-production, proudly unserious when needed, but still curated with enough taste to make the smaller names worth your time.
