John Summit’s Experts Only Festival returns to Randall’s Island Park on September 19–20, 2026, for its highly anticipated second edition. Following a sold-out 2025 debut that drew more than 50,000 fans, the two-day event is expanding its production across three stages. Summit continues to curate a diverse sonic landscape, blending house, bass, techno, and indie dance. With tickets currently on sale, the weekend promises to be a massive gathering for fans eager to catch sets from Summit himself—both as a solo act and as part of the SUBJOHNICS project with Subtronics—alongside a stacked supporting lineup.
Here are five standout acts worth looking out for on this year’s lineup.
Rohaan
UK producer Rohaan delivers boundary-pushing bass that fluidly moves between drum & bass, deep dubstep, grime, and experimental hybrids. His debut album Bleach earned significant critical acclaim, with support from heavyweights like Four Tet, Fred again.., Jamie xx, and Zeds Dead. Expect dynamic, unpredictable sets full of pressure and texture that stand out on the festival’s bass-leaning stages.
LYNY
Chicago’s Alec Leinhauser, known as LYNY, has emerged as a key voice in modern bass and trap-leaning electronic music. His productions, including his 2025 debut album Noise To Dance To, feature wonky, melodic, and heavy hybrid sounds. His sets bring inventive low-end pressure and festival-ready drops that keep the dancefloor locked in.
Partiboi69
Melbourne’s Partiboi69 brings chaotic, high-energy electro, techno, and “ghetto freak” vibes to the stage. Known for his larger-than-life persona and infectious dancefloor tracks, he delivers sets full of attitude, rapid edits, and party-starting aggression. His presence adds an underground-to-festival crossover edge that thrives in outdoor environments.
GRiZ
Following his hiatus, GRiZ returns with his signature future-funk sound—sax-driven, soulful, and bass-heavy. His 2026 album Future Funk Volume 1 leans into heavier bass while maintaining the uplifting core that built his dedicated following. Expect a full-band energy feel, improvisational flair, and impactful drops that blend funk and soul.
Jackie Hollander
Rising star Jackie Hollander has quickly become a force in tech-house and melodic house. With releases on major imprints like Nervous and REALM, her tracks showcase driving, exuberant grooves. Her sets deliver hypnotic, bass-forward energy ideal for sunset slots, characterized by rolling basslines and feel-good momentum.
