Following the success of the 2024 San Diego 4EVR shows and the massive 2025 debut of Niteharts Festival, hometown legends Knock2 and ISOxo are officially returning to San Diego’s Snapdragon Stadium. The duo has announced an expanded, three-day edition of the festival scheduled for October 9, 10, and 11, 2026.
The in-demand pair has curated an exciting lineup spanning the worlds of EDM and Hyperpop. Beyond headlining their own festival, the weekend will feature a special ISOxo ‘H.C.D.’ (Hardcore Diva) set, a highly anticipated Knock2 B2B with DJ Snake, and one of the year’s few exclusive ISOKNOCK performances.
The headlining roster is further bolstered by Porter Robinson (DJ Set), 2Hollis, and RL Grime, all of whom are expected to maintain the high-octane energy that defined the festival’s inaugural year. Supporting acts include Frost Children (DJ Set), Devault, LYNY, Thaiboy Digital & SWEDM, Nitepunk, and Hamdi. In keeping with the tradition established last year, Niteharts encourages attendees to arrive early, with opening sets from either Knock2 or ISOxo kicking off the festivities each day.
With the festival utilizing a single-stage format, attendees can enjoy the full lineup without the stress of set conflicts. While three-day passes sold out shortly after their February release, Niteharts has partnered with Ticketmaster to provide an official resale platform. Limited single-day tickets are scheduled to go on sale Friday, August 7, at 10 AM PST via the official Niteharts website.
