Open'er Festival 2027 in Gdynia, Poland, has received another major addition to its lineup. On October 8, 2026, organizers confirmed five acts: The Chemical Brothers, Ellie Goulding, 5 Seconds of Summer, Adéla and underscores. The most symbolically significant addition is the return of British electronic duo The Chemical Brothers, who will close the Orange Main Stage program on Thursday, July 1, 2027. Their performance has been announced exactly 25 years after their appearance at the first edition of Open'er, an event that has since grown into one of Europe's most recognizable music festivals. The latest confirmations also expand the lineup into pop, rock and contemporary alternative electronic music.
The festival is scheduled to take place from Wednesday, June 30, to Saturday, July 3, 2027, at the Gdynia-Kosakowo airfield on Poland's Baltic coast. According to the published schedule, 5 Seconds of Summer will join Thursday's lineup, Adéla will perform on Friday, and Ellie Goulding and underscores are scheduled for Saturday. The new names follow earlier confirmations of Tame Impala, sombr, The Neighbourhood, RAYE and Patti Smith Quartet. The previously announced performances are spread across several stages, demonstrating that the October 8 announcement is not the final daily schedule but another step in shaping the festival lineup. Exact performance times for individual concerts have not yet been provided in the published artist overview.
The Chemical Brothers return to the festival they have been associated with since its beginning
British duo Tom Rowlands and Ed Simons are among the key musical acts that brought electronic dance music to large concert audiences during the 1990s. Their work combines club culture, powerful rhythms, psychedelic layers of sound and large-scale audiovisual stage production. Some of the most recognizable tracks in their catalog include "Block Rockin' Beats", "Hey Boy Hey Girl", "Galvanize", "Wide Open" and "Got to Keep On". Open'er organizers highlight precisely this combination of music and visual performance as the reason why the duo will headline the closing part of the main stage program on July 1. However, the announcement does not reveal which songs they will perform in Gdynia, so their previous hits serve as an overview of their career rather than a confirmed setlist.
The return has an interesting historical background. According to the festival's official chronology, the first edition took place in 2002 as a one-day event in Warsaw, when The Chemical Brothers performed in Poland for the first time. The festival moved to Gdynia in 2003, initially to Skwer Kościuszki, while since 2006 it has been held at the airfield in the Babie Doły and Kosakowo area. The 2027 performance therefore connects the festival's beginnings in Warsaw with its present-day large-scale edition on the Baltic coast. It is important to distinguish the anniversary of the first performance in 2002 from the venue itself: the original concert did not take place at the festival's current location.
Over the years, The Chemical Brothers have remained more than just a name associated with Open'er's beginnings. The official festival history also records their performance in 2008, when the event already featured multiple stages and attracted tens of thousands of visitors. The duo had also been announced for the 2022 edition, but their performance was canceled due to COVID-19 cases among their crew, and Peggy Gou replaced them. The upcoming concert is therefore not merely a nostalgic reminder of 2002, but also a renewed encounter with the audience following an earlier appearance that never took place. Organizers have announced that they will close the Orange Main Stage, but details of the production and concert duration have not yet been released.
Ellie Goulding and 5 Seconds of Summer bring two different approaches to pop-rock
Ellie Goulding will perform on Saturday, July 3, on the Orange Main Stage, the festival has confirmed in its individual artist schedule. Since her 2010 album "Lights", the British singer has developed a career encompassing electropop, dance music and collaborations with producers working in different styles. Her songs "Starry Eyed", "Lights", "Burn", "Love Me Like You Do" and "Close to Me" have become recognizable parts of the international pop repertoire. The festival profile also mentions her sixth studio album, "I Know Too Much", released in September 2026, as a continuation of a discography that has expanded beyond the boundaries of a single genre over the years. Her appearance adds to the closing night an artist whose music is associated with both mainstream radio pop and electronic dance production.
Australian band 5 Seconds of Summer has been confirmed for Thursday, July 1, also on the main stage. The band was formed in Sydney by Luke Hemmings, Michael Clifford, Calum Hood and Ashton Irwin, and built an international audience through a combination of pop-punk, melodic rock and contemporary pop. Their well-known songs include "She Looks So Perfect", "Youngblood" and "Teeth", while the album "EVERYONE'S A STAR!", released in 2025, introduced a newer phase of their work. Music outlet Pop Scoop reports that this will be their first appearance at Open'er. Their inclusion on the same festival day as sombr and The Chemical Brothers demonstrates Thursday's musical diversity, although the performance order and exact times have yet to be announced.
Adéla and underscores represent a different side of contemporary pop and electronic music
Among the new names is Adéla, an artist of Slovak origin who is active on the international pop scene. Organizers have scheduled her performance for Friday, July 2, on the Orange Main Stage. Her work combines expressive dance and stage performance, a background in ballet training, and electronic production with personal lyrics. Her festival biography recalls the 2024 single "Homewrecked", the songs "Machine Girl", "Superscar" and "SexOnTheBeat", as well as the 2025 EP "The Provocateur". The October announcement particularly highlights her debut full-length album "PRIMA", which marks a new stage in her discography.
Another interesting addition to the lineup is underscores, the stage name of American musician April Harper Grey. According to the official program, she will perform on Saturday, July 3, on the Alter Stage rather than the Orange Main Stage. Her music combines elements of hyperpop, electronic music, dance, indie rock, shoegaze and punk, making it difficult to place within a single genre. After her early independent releases, she attracted attention with the albums "fishmonger" and "Wallsocket", while organizers highlight the album "U" among her more recent works. The confirmation of this performance shows that, alongside major main-stage acts, Open'er continues to provide space for projects whose audiences have emerged at the intersection of internet music culture and the alternative scene.
What the schedule currently looks like from June 30 to July 3
On Wednesday, June 30, Tame Impala, the Australian project of Kevin Parker, is scheduled to perform on the Orange Main Stage, having been announced back in August as the first major name for the 2027 edition. The following day, Thursday, sombr, 5 Seconds of Summer and The Chemical Brothers are confirmed for the same stage. Patti Smith Quartet is also scheduled to perform on the Tent Stage that day, offering the possibility of a completely different concert experience away from the main stage. On Friday, July 2, The Neighbourhood and Adéla will share the main stage. On the final day, Saturday, July 3, RAYE and Ellie Goulding are listed for that stage, while underscores is scheduled to perform on the Alter Stage.
This overview presents the dates and stages of the artists confirmed so far, but it does not represent a completed festival schedule. In a September announcement, festival founder Mikołaj Ziółkowski stated that Open'er was changing the way it presents its main acts for the 2027 edition and that there could be up to three artists with headliner status on a single day. This differs from the previous model, in which one or two main acts per day were generally highlighted. The announcement of The Chemical Brothers as additional Thursday headliners fits into this planned change. Nevertheless, the number of new confirmations does not mean that all stages and daily performance slots have already been filled.
A festival that grew from a one-day event in Warsaw
Since 2002, Open'er has evolved from a one-day concert into a multi-day international event. Following its move to Gdynia in 2003, the program gradually expanded, while the new airfield location introduced in 2006 enabled the development of a larger festival site. The four-day format was introduced in 2009, according to the event's official history. Over the years, artists from very different generations and genres have performed there, from Prince and Björk to Radiohead, Arctic Monkeys, Muse and numerous contemporary pop and hip-hop acts. This history explains why the current announcements for 2027 do not follow just one musical direction, but deliberately bring together established performers and emerging names.
According to organizers, the 2025 edition attracted approximately 140,000 visitors over four days, with performances by artists such as Linkin Park, Nine Inch Nails, Massive Attack and Muse among its highlights. The official historical overview also mentions accompanying cultural activities, including theater, artistic programs and social initiatives. This is an important part of Open'er's identity: it is an event whose content extends far beyond an individual concert on the main stage. Nevertheless, for 2027 it is necessary to distinguish the festival's long-standing tradition from the program already explicitly confirmed for the next edition. Specific accompanying activities, as well as possible additional musical acts, will become clearer following further announcements from organizers.
Tickets for Open'er 2027: one-day, two-day and four-day options
According to the official price list for the 2027 edition, Regular category tickets are now on sale following the sellout of the earlier, more affordable Early Bird category. Published base prices are 565 Polish zlotys for a one-day ticket, 855 zlotys for a two-day ticket and 1,185 zlotys for a four-day ticket. Categories that include access to the festival campsite are also available: the four-day package is listed at 1,455 zlotys, while the two-day package costs 1,035 zlotys. Organizers specify an additional five percent service fee on top of these amounts, meaning the final purchase price may be higher than the initially displayed price. Prices are expressed in Polish currency, and the availability of individual categories depends on ticket allocations.
Two-day tickets cover three consecutive combinations of days: June 30 and July 1, July 1 and 2, or July 2 and 3. For those particularly interested in The Chemical Brothers, Thursday or a package including July 1 is relevant, while Ellie Goulding and underscores appear on Saturday's schedule. As emphasized on the official website, a ticket grants access to the festival program during the period for which it is valid, rather than to one individual concert. Organizers also warn about the risks of purchasing tickets outside authorized sales channels. Since the festival is still several months away, the schedule, availability and entry conditions should be monitored through subsequent announcements.
Gdynia and the Baltic coast as a destination for festivalgoers
Open'er takes place in Gdynia, a city in northern Poland that, together with Gdańsk and Sopot, forms part of the wider metropolitan area known as Trójmiasto, or the Tri-City of Gdańsk - Gdynia - Sopot. The festival site at Gdynia-Kosakowo airfield is not the same as Gdańsk's passenger airport, an important distinction when planning an international journey. Visitors planning to attend for several days may consider staying in Gdynia or other parts of this coastal area, depending on their preferred way of traveling to and from the concerts. Accommodation offers in Gdynia and the surrounding area can serve as a starting point for travel planning, together with checking transport connections to the festival site. Organizers usually publish detailed practical information about access to the venue, but specific instructions and transport arrangements for 2027 should be checked once they have been officially announced.
The October 8 announcement brought five new acts, but more importantly, it clarified their distribution across festival days and stages. The Chemical Brothers on Thursday connect Open'er's beginnings in 2002 with its current position on the European festival map, while Ellie Goulding, 5 Seconds of Summer, Adéla and underscores broaden the musical range of the confirmed lineup. Tame Impala, sombr, The Neighbourhood, RAYE and Patti Smith Quartet have already provided a strong initial framework for the four-day edition. Future announcements will reveal how the remaining performance slots will be distributed between the main and smaller stages. For now, it has been confirmed that Open'er Festival 2027 will take place from June 30 to July 3 at Gdynia-Kosakowo airfield.
