Less than two years ago, Knock2 and ISOxo were underground favorites in the EDM community, each cultivating die-hard fan bases with their distinctive styles rooted in trap and bass house. Now, the duo is headlining renowned festivals such as Coachella and EDC, and going beyond the main stage with the launch of their own hometown festival. With some of the biggest names in EDM history, Skrillex and Zedd joining them for B2B sets, Knock2 and ISOxo aren’t just throwing a festival—they’re making a statement.
The NITEHARTS festival was hinted at earlier this year during ISOKNOCK’s two-day event at Snapdragon Stadium, the same venue that will host NITEHARTS. That event, dubbed “San Diego 4EVR” saw two nights of sold-out crowds. At the close, a QR code referencing the upcoming NITEHARTS festival flashed on screen, and Knock2 proclaimed, “See you next year” before leaving the stage.
Hosting another show in San Diego carries special significance for these artists. It’s the place where they met as teenagers, began producing music, and the city that supported them from the very beginning. With NITEHARTS, they once again shine a spotlight on San Diego and look to further cement their hometown legacy in the process.

The lineup for NITEHARTS exemplifies the duo’s meteoric rise. Both artists’ rapid ascent from playing night club shows to headlining EDC together as a mystery act is truly remarkable. The young stars have built a devoted following by merging their innovative trap and bass house sound with some of the most high-energy and electrifying performances in recent memory. With tracks like Knock2’s “Dashstar” and the duo’s “SMACK TALK” becoming festival anthems, their influence is obvious, and their trajectory shows no signs of slowing.

The addition of Skrillex and Zedd to the lineup truly underscores that Knock2 and ISOXO have reached the status of EDM superstars. These globally recognised icons have helped shape the sound of EDM and expanded the reach of dance music over the past decade. Their participation in NITEHARTS as B2B artists proves that ISOKNOCK is no longer just a pair of rising stars.
As Knock2 and ISOxo continue to bring their journey full circle, their story is more than just a rise to fame—it’s a meteoric one.
