Matt Berninger, Kneecap, ¥ØU$UK€ ¥UK1MAT$U & more join Open’er 2026 lineup

It’s a new year, so that can mean only one thing: there are more new names for Open’er 2026! The huge Polish event has added another five acts to its bill including The National frontman Matt Berninger, Northern Irish rabble-rousers Kneecap, and Japanese DJ ¥ØU$UK€ ¥UK1MAT$U.

The other acts added to the lineup today include New York songwriter LP, as well as electronic icon Martin Garrix. They’ll be joining the likes of Nick Cave & The Bad Seeds, The Cure, The xx, David Byrne, and Ethel Cain, who have all already been announced for this summer’s event, as well as pop superstars JADE, Addison Rae and PinkPantheress and loads more huge names.

This year’s edition of Open’er will take place from 1st-4th July and will once again return to the Gdynia-Kosakowo Airfield in Poland’s Gdynia. Obviously there are still lots more acts to be announced, but in the meantime, you can get your hands on tickets by heading over to the festival’s website now. 

While we get ready for this year’s fest, remind yourself of all the action from last summer’s huge weekend below.
