The skies opened up on the final day of Open'er Festival 2026 in Gdynia-Kosakowo Airfield, Poland, and with it poured a tidal wave of pop greatness. K-pop icon JENNIE took the Main Stage by storm, her solo headline performance a masterclass in progressive pop that left even the most seasoned festival-goers awestruck. The American pop sensation Addison Rae was no less electrifying, bringing her A-game to the stage with an energetic set that had fans dancing and singing along from start to finish.
JENNIE's show was a blistering display of confidence, charisma, and musical prowess. Despite having only one album under her belt – 'Ruby' – and limited solo headline gigs, she commanded the crowd with the same authority as some of the biggest names in the business. Highlights included an apocalyptic intro video that set the tone for her energetic performance, the self-love anthem 'Filter', and a closing rap-infused track that left fans begging for more. A notable moment saw her remixing Tame Impala's 'Dracula', which sent the crowd into raptures.
Among the many highlights was the debut of three unreleased solo tracks – 'Lock It Down', 'Heaven', and 'Less Than A Lover' – a bold move that left fans eagerly anticipating new music from this talented artist. JENNIE also subtly nodded to her BLACKPINK roots, with tracks like 'Mantra' featuring slick dance breakdowns and a highly catchy chorus. But it was clear that she's now forging her own path, creating a distinct identity on stage that resonated deeply with the crowd.
Addison Rae, the TikTok sensation turned pop star, brought her signature blend of sass, sparkle, and sonic excess to the stage. Her performance was an unapologetic love letter to shameless pop, complete with sugary hooks, infectious beats, and a healthy dose of mischief. Having risen to fame in record time, Rae has already proven herself as a force to be reckoned with, performing at major venues and collaborating with top artists like Charli XCX.
The Open'er Festival 2026 lineup was a veritable who's who of music greats, featuring the likes of Calvin Harris, Nick Cave And The Bad Seeds, Florence & The Machine, and The xx. But it was clear that pop music is now firmly in the driving seat, with JENNIE and Addison Rae leading the charge alongside other rising stars like PinkPantheress, Jade, Peggy Gou, and Horsegiirl.
The festival's emphasis on pop may have been a departure from previous years, but it was undeniable – this is an era where contemporary pop music reigns supreme. And with JENNIE and Addison Rae at the forefront of this movement, one thing's for sure: pop will continue to be the sound of the summer for years to come.
