Open’er 2027 adds The Chemical Brothers, Ellie Goulding and 5 Seconds of Summer

Open’er Festival has announced a new group of artists for its 2027 edition at Gdynia-Kosakowo Airfield. The event runs from 30 June to 3 July, and the latest wave adds The Chemical Brothers, Ellie Goulding, Adéla, 5 Seconds of Summer and underscores.

The Chemical Brothers will headline Thursday and close the Orange Main Stage. The booking carries a strong anniversary narrative: the duo also performed at the festival’s first edition 25 years earlier. It is both a major electronic-music booking and a piece of brand history that Open’er can activate across editorial, social and on-site channels.

The announcement deliberately broadens the audience. Ellie Goulding and 5 Seconds of Summer bring mainstream pop reach, while Adéla and underscores add emerging and alternative momentum. That mix allows the festival to serve several fan communities within one campaign rather than depending on a single genre.

Regular tickets are currently on sale through the official Open’er ticket page. At the time of verification, a four-day ticket is listed at 1,185 PLN before the stated 5% service fee; camping and accommodation options are sold separately or in bundled formats. Buyers should use the official sales channels linked by the organiser.

Commercially, the 25-year return of The Chemical Brothers creates a ready-made content platform for sponsors: archive-to-present storytelling, electronic-music experiences and loyalty campaigns for long-term visitors. The broader line-up also supports segmented offers for travel, mobile, payment and accommodation partners.

No external publicity image was used because the official pages did not provide documented republication terms for the available visuals. FestivalTV is publishing the verified report in a clean text-only format.
