Whethan brought a heavier, bass-and-hip-hop-leaning DJ set to SoCal's Splash House festival, which returned to Palm Springs, California, across back-to-back weekends in mid-August 2026. The producer used the poolside party, usually associated with lighter electronic music, to showcase harder-edged sounds, and Billboard has now released his full 90-minute set for fans to listen to online.

Highlights of the set included a glitchy edit of Avicii's "Levels," a heavy remix of Gucci Mane and Waka Flocka Flame's 2011 track "15th and the 1st," and unreleased new music made with fellow producer Subtronics, which appears roughly 29 minutes in. Whethan also played his own viral 2025 edit of Fast Life Yungstaz's "Swag Surfin," which became a standout moment of the show after he spotted a custom banner referencing the song hanging from a nearby hotel balcony. The wider Splash House 2026 line-up included Kettama, Riordon, Prospa, Alison Wonderland and Tiga, among others.
