Electronic dance music artist Underworld is back with brand new music, and this time they’ve teamed up with fast-rising Dutch techno artist KI/KI for an explosive new collaborative single called “ARP12.” The track arrived on May 15 through Smith Hyde Productions and debuted alongside a livestream tied to the duo’s appearance at EDC Las Vegas.
“ARP12” feels built for giant festival stages and sweaty warehouse parties. The song features pulsing synths, hypnotic melodies, and pounding beats that consistently push forward. You can hear both artists all over it: Underworld brings their classic atmospheric electronic sound while KI/KI adds the hard-hitting, high-speed energy that has made her one of the most talked-about names in dance music right now.
The video matches that intensity perfectly. Filled with neon lights and a carved smile, the music plays out like being dropped directly into the middle of a massive late-night festival set. There’s no real storyline here other than the visuals are more about capturing the feeling of the track itself: loud, energetic, and completely locked into the dancefloor. This new single marks Underworld’s first new release since their 2024 album Strawberry Hotel, and arrives as the legendary electronic duo gears up for a huge run of international tour dates throughout 2026. The group will hit festivals including Creamfields Festival, Sziget Festival and III Points, along with several headline appearances across the U.S. and Europe.
