Following a successful first edition in 2025, Experts Only Festival returns to Randall’s Island Park in New York City on September 19–20. Organizers have now shared the full set times for its second year, covering three stages across the weekend. John Summit appears on both days alongside GRiZ, Subtronics, Levity, Adam Ten b2b Max Styler, Innellea b2b Korolova, Prospa, Partiboi69, Will Clarke and more. Sunday has also attracted extra attention after John Summit teased a possible closing appearance with GRiZ and Subtronics.

Experts Only Festival 2026 Set Times

For the opening day, John Summit will close the Main Stage with an extended set beginning at 7:30 PM. Adam Ten b2b Max Styler perform before him, while Levity plays later in the evening on the Mirror Field. Lost New York brings more bass music into Saturday through sets from LYNY, Taiki Nulight and Rohaan.

After his extended Saturday performance, John Summit returns on Sunday for a sunset set at 6:05 PM. GRiZ follows at 7:25 PM, before SUBJOHNICS closes the Main Stage from 8:45 PM. The b2b pairs John Summit with Subtronics, bringing them together again for the festival’s final scheduled performance. Their position directly after GRiZ becomes particularly interesting once John Summit’s recent comments enter the conversation.

Across both days, the second edition also brings a stronger bass presence alongside the house and techno associated with Experts Only. GRiZ, Subtronics, Levity, LYNY, Taiki Nulight and Rohaan represent that side of the weekend. Meanwhile, Prospa, Partiboi69, Will Clarke, Jackie Hollander, Devault and Innellea b2b Korolova add more house and techno across the three stages. The festival returns after its sold-out 2025 debut welcomed more than 50,000 attendees to Randall’s Island Park.

Could GRiZ Join SUBJOHNICS for a Surprise Closing B3B?

Speculation over Sunday’s final set grew after John Summit recently discussed the festival on Experts Only radio.  While speaking about the closing moments, he said it would be “Subtronics, GRiZ, and me to close it out.” His wording suggested that the scheduled SUBJOHNICS performance could involve more than just himself and Subtronics.

There is already plenty of excitement around SUBJOHNICS given the history between John Summit and Subtronics. The pair have performed together under the name since 2022, combining their different sides of electronic music. Their previous appearances include the well-known EDC Las Vegas 2023 b2b and several festival performances since then. Their return at Experts Only Festival already gave Sunday plenty of interest before John Summit mentioned GRiZ.

A possible three-way set would also bring together two artists with their own collaborative history. GRiZ and Subtronics have worked together on Griztronics and later releases. GRiZ performs immediately before SUBJOHNICS, giving him an easy opportunity to remain involved once the closing set begins. John Summit’s comments are what give that possibility more weight than speculation based only on the timetable.

Although organizers have not confirmed a John Summit b2b Subtronics b2b GRiZ performance, the tease adds more excitement to Sunday’s closing set. Bringing all three together would be a fitting surprise for the second edition of Experts Only Festival. It would also mark the first appearance of what has already been informally dubbed GRIZJOHNICS.
