Wednesday 30th June to Saturday 3rd July will mark the 2027 edition of Open'er Festival, which is set to return to Gdynia’s Baltic coast. And ahead of the festival's awaited return, they have added more names to their growing lineup. Including legendary electronic duo The Chemical Brothers, who will be returning to Open'er exactly 25 years later to headline the Main Stage on Thursday.
Plus Ellie Goulding, pop newcomer Adéla, Australian rock and pop band 5 Seconds of Summer, and genre-defying electronic artist Underscores.

The added artists join a lineup of previously announced names, Tame Impala, Sombr, The Neighbourhood, RAYE and Patti Smith Quartet, who will be continuing Open’er’s tradition of bringing together some of the biggest and most influential names across generations and genres.
Coming from its humble beginnings in Warsaw in 2002, Open’er has grown into one of Europe’s biggest and most internationally recognised music festivals, bringing together global superstars, emerging artists and some of the most influential names in contemporary music.
