On October 3, 2026, COS Torwar trades its usual sporting hardwood for the unhinged, glitter-strobed chaos of Joost Klein, as the Dutch provocateur brings his World Tour to Warsaw for the first time. Originally slated for two nights back in June, the rescheduled date lands as a single, unmissable Saturday night event — and if anything, the wait has only sharpened the anticipation. Few artists on the current European circuit combine hyperpop production, live-band hip hop energy, and full-blown theatrical spectacle quite like Joost, and Torwar’s tighter arena walls promise an intensity that a stadium show simply can’t replicate.

Expect a setlist built around the breakneck, genre-hopping catalogue that made Joost a global name — the raucous, Eurovision-adjacent anthem “Europapa” included — stitched together with the kind of maximalist visual production, costume changes, and barely-contained stage chaos that has become his signature. This isn’t a rapper standing behind a mic: it’s a full sensory event, part rave, part cabaret, part fever dream, delivered with the manic charisma that turned a kid from Leeuwarden into one of Europe’s most talked-about live acts.

For Warsaw’s audience, this is a chance to catch an artist at the exact moment he’s crossing over from internet-native cult favorite to genuine arena headliner — and to do it in the close confines of Torwar rather than a stadium built for tens of thousands. Expect a crowd that skews young, loud, and fluent in every lyric, and a night that will be remembered as the show where Joost Klein properly arrived in Poland.
