Niteharts Reveals Powerful 2026 Lineup for Festival’s Return

Following the success of the 2024 San Diego 4EVR shows and the monumental 2025 debut of Niteharts Festival, hometown legends Knock2 and ISOxo are set to return to San Diego’s Snapdragon Stadium. The festival will expand into a massive three-day experience, taking place on October 9, 10, and 11, 2026.

The duo has curated an exceptionally high-energy lineup that bridges the gap between EDM and Hyperpop. Fans can look forward to a series of exclusive performances, including ISOxo’s highly anticipated ‘H.C.D.’ (Hardcore Diva) set, a collaborative Knock2 B2B with DJ Snake, and one of the rare ISOKNOCK appearances of the year.

The headlining roster is further bolstered by the inclusion of Porter Robinson (DJ Set), 2Hollis, and RL Grime, ensuring the intensity remains high throughout the weekend. The supporting lineup features a diverse array of talent, including Frost Children (DJ Set), Devault, LYNY, Thaiboy Digital & SWEDM, Nitepunk, and Hamdi. Staying true to the festival’s tradition, organizers are encouraging attendees to arrive early, with special opening sets from Knock2 or ISOxo scheduled to kick off the festivities each day.

With the festival utilizing a single-stage format, attendees will not have to worry about conflicting set times, allowing for a seamless experience. While three-day passes were snapped up almost instantly back in February, those still looking to attend can utilize the official resale platform via Ticketmaster. Additionally, limited single-day tickets are scheduled to go on sale on Friday, August 7, at 10 AM PST through the official Niteharts website.
