ISOKNOCK Unveils Niteharts Festival Lineup Featuring B2Bs With Skrillex, Zedd, and More

What began as a promise during a sold-out homecoming weekend last December is now official: ISOxo and Knock2 are launching their own festival, Niteharts, landing in San Diego this October.

The two-day event will take over San Diego State University’s Snapdragon Stadium on October 11 and 12, 2025, transforming last year’s “San Diego 4EVER” into a curated festival built by two local powerhouses. Each night features solo sets from ISOxo and Knock2, followed by rare back-to-back performances. ISOxo will go B2B with Skrillex while Knock2 returns to the decks with Zedd.

ISOxo and Skrillex have recently collaborated on Skrillex's latest album and have a stack of unreleased collaborations that fans have been waiting to hear live. Knock2 and Zedd, on the other hand, tested the waters last year during an unexpected B2B at Washington D.C.'s Echostage, a set that had fans asking for more before the night even wrapped.

The rest of the lineup pulls from across the spectrum of trap, club, and experimental bass, with performances from JOYRYDE, Yellow Claw, horsegiirL, RIRIA, Syzy, Kenny Beats, Starjunk 95, Baby Jane, and ericdoa. Also on the bill are two special B2Bs: FrostTop with RemK, and WINK with Nikko.

Hints of the festival first surfaced earlier this summer, when fans driving through Nevada spotted a cryptic Niteharts billboard on I-15. Now, the reveal confirms what many hoped for following ISOKNOCK’s gravity-defying set at North Coast Music Festival and their packed Sahara Tent takeover at Coachella last year.

Together, Knock2 and ISOxo are alumni of EDM.com’s Class of 2022 and 2023, respectively. They have redrawn the boundaries of trap and bass house, pushing their sound through stadiums, festival stages, clubs, and warehouses alike at breakneck speed. Their joint album, “4EVER,” arrived as a surprise last August and captured the voracious momentum that has defined their collective rise. Niteharts is the natural next move, a hometown return, shaped entirely on their own terms.

Presale registration is open now at niteharts.com. Tickets go on sale Wednesday, July 9th, 2025, at 10 AM PST.
