The Arp12 collaboration between Underworld and KI/KI (live version) is now available on Underworld’s YouTube channel, and the single was originally released on May 15. The accompanying video was filmed in a hangar in the English countryside, and members Karl Hyde and Rick Smith of Underworld are noted to frequent hangars in Essex where they store their machines.

KI/KI is described as drawing on trance and rave influences and has collaborated with artists including Marlon Hoffstadt and Armin van Buuren, and the single had appeared on the duo’s live tracklist for over a year under the name “Arpaggio12.” Underworld’s 2024 album Strawberry Hotel is referenced as their most recent release prior to this collaboration, and an Instagram post is linked to the live release.
