About the festival

The festival market in Poland encompasses well-established, large-scale music events with long traditions, as well as newer ones catering to younger audiences, all typically taking place during the summer season. However, Poland has lacked a major indoor event in the autumn with a diverse music program, akin to European brands like Iceland Airwaves, Sonar, Meltdown, Le Guess Who?, or Pitchfork Festival Paris.

Inside Seaside has filled and pioneered this festival niche.

It’s a two-day music celebration featuring both international and Polish artists. Thanks to its enclosed indoor venue, there’s no need to worry about weather conditions. The festival first took place in 2023, attracting a total of 12,000 attendees. During its second edition, this number increased to 18,000.

Among the bands that have performed at Inside Seaside are IDLES, The Last Dinner Party, Girl in Red, RY X, Black Pumas, Nothing But Thieves, Sleaford Mods, Tom Odell, Nils Frahm, Ezra Collective, Hania Rani, Sprints, Artur Rojek, Vito Bambino and Monika Brodka.

The festival is held in specially adapted halls at AmberExpo, where, in comfortable conditions over two days, on three stages, leading Polish and international electronic, rock, and jazz artists perform. But that’s not all: festival-goers can meet guests from Radio 357’s Discussion Zone, watch film screenings in the Cinema, participate in the Poster Fair, visit art exhibitions, explore the fashion zone, or purchase vinyl records. Inside Seaside is an indoor festival unlike any other in Poland – we encourage you to spend a weekend in a space buzzing with music and non-musical attractions.

The festival is co-created by the team at Radio 357, the most frequently chosen internet radio station in Poland, funded by its listeners. We encourage you to listen to broadcasts dedicated to Inside Seaside, participate in contests, and, most importantly, meet the journalists who will conduct interviews with artists, host music, film, and culinary shows, as well as silent discos during the festival.

The City of Gdańsk is able to accommodate many cultures, traditions, and histories, combining them into a new quality. Here, in the City of Freedom, at the crossroads of European routes, an extraordinary art scene has flourished for years. It’s a modern and open metropolis with incredible potential, which has world-class music in its DNA.

The festival’s sponsors are ERGO Hestia and Invest Komfort.
