Experts Only Festival is John Summit's dance music festival at Randall's Island Park in New York City. Its second edition took place on Saturday, September 19 and Sunday, September 20, 2026, following the festival's 2025 debut on the same island. The official site billed it as NYC's largest dance music festival, and the official FAQ said Summit curated the weekend and took the stage following the release of his album CTRL ESCAPE. The 2026 edition was produced in partnership with Medium Rare, Relentless Beats and EMW, and music ran from 3 PM to 10 PM each day.
The official lineup and set times pages named 31 artists across the two days. John Summit played both days: Saturday ended with his extended set on the Main Stage, and on Sunday he played a sunset set before the Main Stage's last slot, SUBJOHNICS, his back-to-back with Subtronics. The set times also billed Adam Ten b2b Max Styler on Saturday and Innellea b2b Korolova on Sunday. Saturday also featured Levity, LYNY, Taiki Nulight and more, while GRiZ, Partiboi69 and Will Clarke were on the Sunday bill.
The official set times split the weekend across three stages, which co-producer Relentless Beats described ahead of the festival. The Main Stage was home to Summit's headline sets and mixed house, techno, indie dance and bass music. Mirror Field was a separate stage surrounded by art installations, built around emerging talent and a wider mix of electronic artists. The Pwemium Lounge, inspired by the viral 'Pwemium' meme, was an indie dance space with its own design and programming.
