15 May 2026, 09:59 | Written by Best Fit

Underworld have released a new collaboration with Dutch techno-trance artist KI/KI, titled "Arp12", alongside a livestream from EDC Las Vegas.

"Arp12" is Underworld’s first new music since their 2024 album Strawberry Hotel. The release marks the beginning of a busy run of international shows throughout 2026, with dates across North America, South America, and Europe. These include festival appearances at Sziget in Budapest, Øya in Oslo, Creamfields in Cheshire, and a two-night stand at New York’s Knockdown Center on 3 and 4 September (the second of which is sold out).

For more than three decades, Underworld have remained a consistent presence in electronic music, known for their live performances and studio production. "Arp12" continues that trajectory with a straightforward club-focused approach, bridging the duo’s history with KI/KI’s contemporary trance influence.

The full list of upcoming tour dates includes shows from May through October, spanning the US, Colombia, Serbia, Bulgaria, Ireland, Spain, Hungary, Portugal, Norway, France, and the UK.
