BitterSweet Festival 2025: 6 Artists We Can’t Wait to See in Poland

BitterSweet Festival is take place this August in Poland with a stacked lineup that mixes global stars, cult favorites, and local legends. Across three days (August 14–16), the fest is bringing together artists who know how to put on a show, whether you’re in it for the beats, the emotional anthems, or the unpredictable stage antics. Here’s a look at six artists we’re especially hyped to catch live this year, and why you should make time for them in your schedule.

Post Malone (August 15)

Post Malone has evolved from chart-topping hit-maker to genre-hopping headliner. He’s still riding high off Austin and F-1 Trillion, his 2023 and 2024 album that leaned more into alt-rock and country than hip-hop. Whether he’s crooning with an acoustic guitar or running through “Rockstar,” you never quite know what version of Post you’ll get on stage, and that’s part of the fun.
Expect a set that spans his genre-bending catalog. He’s a born entertainer, equal parts heartfelt and chaotic. He might shotgun a beer mid-song. He might cry. He might do both. Either way, his shows feel big emotionally and literally.

Loreen (August 16)

Loreen has always known how to make a moment. She’s a two-time Eurovision champion, most recently winning in 2023 with “Tattoo,” which became a pan-European smash. Her live shows are performance art with fog, strobe lights, and serious drama.
Since her Eurovision win, she’s continued touring across Europe and dropped a string of moody, synth-heavy singles that double down on her theatrical side. There’s real power behind her voice and vision. She’ll bring a sense of high-stakes spectacle to the stage, and there’s a good chance you’ll walk away feeling like you just witnessed something closer to a ritual than a pop concert.

Marc Rebillet (August 15)

Marc Rebillet is chaos in silk robes (and we mean that as a compliment). The improvisational loop artist has carved out a niche somewhere between comedy, club beats, and pure madness. He builds songs on the fly, takes requests from the crowd, and usually ends up dancing in his underwear. It’s unhinged and hilarious.
Lately, he’s been popping up at festivals all over the world, often stealing the show from artists with twice the budget. No two sets are ever the same, and that’s the point. Whether he’s freestyling about Polish food or looping a beat built from someone yelling “BITTERSWEET,” you’re in for a ride.

Nelly Furtado (August 14)

After a long hiatus, Nelly Furtado is officially back. She’s been playing select live dates over lately, including buzzy appearances like her own DJ sets. This past year has been the return of loose Nelly, the clubby, confident side that gave us “Promiscuous” and “Maneater.”
Her catalog is deep, and there’s something undeniably satisfying about hearing those early 2000s hits blasted from a festival stage. If she slips in a surprise new track or two, we won’t be mad. And if you don’t lose your mind when the “Say It Right” synth kicks in, are you even human?

Viagra Boys (August 16)

Viagra Boys make music for people who like their punk sweaty, strange, and just a little satirical. The Swedish band, led by frontman Sebastian Murphy, deliver snarling, bass-heavy tracks about everything from masculinity to… shrimp. Their live shows are loud, sloppy in the best way, and way more fun than you might expect from a band with a name like that.
If you’re tired of polished pop and looking for something that hits like a beer can to the head, this is your stop. Come for the sax solos. Stay for the unfiltered weirdness.

Julia Wieniawa (August 14)

One of Poland’s brightest homegrown stars, Julia Wieniawa brings pop charisma with a local edge. Originally known for her acting, she’s built a legit music career over the past few years. Her latest EP Sobą Tak shows off her polish (no pun intended) as both a vocalist and performer.
She’s a staple on Polish charts, but her appeal is bigger than just the radio. Her stage presence is sleek, and she knows how to command a crowd. BitterSweet gives her a global platform, and there’s no better time to get on board. Consider this your moment to brag, “I saw her before she went international.”

BitterSweet Festival has something for just about everyone. But if you want the kind of sets you’ll still be talking about on the train ride home, keep your eye on these six. They’re bringing heart, spectacle, weirdness, and everything in between. See you in the crowd!
