British modern pop icon Jessie Ware and the duo Hermanos Gutiérrez are the first artists announced for Inside Seaside 2026. Winter Tickets are available until 31 March.
Inside Seaside returns in 2026 with the fourth edition of the Inside Seaside festival and announces the first artists for the fourth edition. On 13 and 14 November in Gdańsk, at AmberExpo, JESSIE WARE and HERMANOS GUTIÉRREZ will perform – artists who, in completely different ways, define the contemporary sound of emotion, elegance, and trance-like energy.
Friday’s headliner, Jessie Ware, has set herself apart on the British pop scene over the past decade, blending soulful vocals with danceable beats and earning a reputation for polished live performances. Her recent albums have cemented her status as an icon of modern disco and pop, with tracks such as “Spotlight” and “Free Yourself” becoming anthems on dancefloors and festival stages. At Inside Seaside, Jessie Ware will bring both her hit-making energy and signature elegance, along with music from her new album “Superbloom”, due out on 17 April.
Hermanos Gutiérrez are brothers Alejandro and Estevan, whose instrumental work transports listeners into cinematic, almost hypnotic landscapes. Their music – inspired by Latin American tradition, westerns, surf rock and ambient – creates a space full of sunshine, melancholy and tranquillity. The duo’s concerts are like a journey without words: atmospheric, focused, captivating. On the festival stage, their guitar dialogues will create a unique counterpoint to Jessie Ware’s danceable energy, showcasing the wide spectrum of emotions that Inside Seaside offers.
Now in its third year, Inside Seaside has filled a niche for autumn festivals in Poland. This two-day indoor music festival has attracted 12,000 attendees since its debut in 2023, rising to 18,000 in subsequent editions.
The festival will take place in the converted spaces of AmberExpo, where leading artists from Poland and around the world will perform on three stages – previous editions have featured acts such as Franz Ferdinand, IDLES, Black Pumas, The Kills, King Gizzard & the Lizard Wizard, Tom Odell, and Hania Rani. In addition to concerts, Inside Seaside offers a cinema, Radio 357’s talk zone, a poster market, exhibitions, fashion, and vinyl, creating a comprehensive musical and cultural experience.
