Underworld team up with KI/KI on new song ‘Arp12’: Listen

Underworld and KI/KI have teamed up on a new song, ‘Arp12’. The British electronic veterans dropped the full-throttle dancefloor cut today, built around hard techno drums, euphoric synth melodies, and a driving, trance-referencing bassline.

‘Arp12’ marks the first release of new material from Underworld since their 2024 album ‘Strawberry Hotel’. The legendary UK outfit have also collaborated with KI/KI for the first time on this one — the Amsterdam-based trance-techno star whose profile has been rising fast across festival and club circuits.

Then this past weekend, Underworld played their EDC Las Vegas 2026 set with ‘Arp12’ premiered live as part of the Smith Hyde block. The set also pulled in a David Lynch tribute and Underworld’s classic ‘Born Slippy’ bookend treatment.

Plus, Underworld have a busy schedule of summer dates lined up. Shows across Europe, North America, and South America stretch through the remainder of the year. Earlier this year, the duo marked 30 years since the release of ‘Born Slippy (Nuxx)’ with a trio of live shows in London, alongside a limited edition vinyl reissue.

Also, the KI/KI link-up sits inside her own busy run. She kicks off her first-ever face-to-face with Armin van Buuren at A State of Trance Vietnam on June 13. Now stream ‘Arp12’ via underworldlive.com or wherever you get your music.
