US pop star Sombr has announced a 2027 UK and European tour, extending his "You Are The Reason" run, days after playing a well-received main-stage set at Reading & Leeds 2026. The tour will include a headline show at London's O2 Arena, with support from Suki Waterhouse, marking a significant step up for the 21-year-old following his breakout single "Back To Friends" and acclaimed debut album "I Barely Know Her".

The European leg opens in Oslo on 8 May and moves through Sweden, Finland, Denmark, Germany, France, Switzerland, Austria and more, with Ravyn Lenae and Jessie Mazin providing support, before closing at London's O2 on 22 June with Waterhouse. Additional UK and Ireland festival dates are set for Dublin's Malahide Castle, Belfast's Belsonic Ormeau Park and Glasgow Summer Sessions in June. Tickets go on general sale on Friday 4 September at 10am local time, with pre-sale beginning Wednesday 3 September.
