Among Poland's biggest, craziest and most popular music festivals, Open'er is best experienced by reserving a campsite and coming prepared for four days of partying in the sun (and the rain) as some of the world's biggest touring acts perform on several stages at the Gdynia-Kosakowo Airfield. Unrivalled in size anywhere in the country, the colossal festival repeatedly curates an extensive lineup ranging from the world's most reputable music stars to budding domestic talent. Past years' line-ups have included Bruno Mars, Gorillaz, Depeche Mode, Massive Attack, Fleet Foxes, David Byrne and many others.

So far, the 2020 line up includes Taylor Swift, Thom Yorke's Tomorrow’s Modern Boxes, A$AP Rocky, Twenty One Pilots, Kendrick Lamar, FKA Twigs, Foals, Martin Garrix, Michael Kiwanuka, Schafter and Big Thief. More great artists to be announced soon! Stay-tuned.
