Ljubljana’s Joker Out marked their tenth anniversary on Saturday with a carnival-style open-air concert that drew 17,000 fans despite torrential rain, technical setbacks and a last-minute storm warning, turning adversity into a defining moment of communal defiance. The Slovenian pop-rock band, fresh from their 2023 Eurovision spotlight, delivered an evening of acrobatics, surprise guests and an emotionally charged finale on Kongresni trg, as hail and lightning forced organisers to consider an abrupt cancellation. “The crowd refused to leave,” reported national broadcaster RTV Slovenija, which described the downpour as a “sudden summer storm” that drenched equipment and sent security teams scrambling for cover. By 22:30 local time the skies had relented, the stage dried, and Joker Out launched into a set that climaxed with a 15-minute encore watched by 1,500 international fans who had travelled from across Europe .
Technical director Jure Koren confirmed that power fluctuations during the opening act briefly silenced the PA system, while lightning sensors triggered a precautionary blackout just as frontman Bojan Cvetrežnik stepped on stage. “We had 90 seconds of silence,” Koren told RTV, “but the crowd started singing *a cappella*—that’s when we knew we had to finish.” The band’s choreographed stunts, including aerial silk routines and confetti cannons, proceeded under umbrellas, while guest vocalists Manca Špik and Senidah joined for a duet that local critics called “a euphoric island in the storm.”
The concert capped a week in which Ljubljana’s summer festival season reached its zenith. On Friday the 74th Ljubljana Festival opened with Puccini’s *Turandot* in a concert staging on Kongresni trg, marking the first time the opera has been performed outdoors in the city’s history . Meanwhile, the Ana Desetnica street arts festival launched its two-week run across 13 Slovenian cities, bringing circus, dance and light installations to public squares and parks .
Joker Out’s anniversary show also underscored the resilience of live music in an era of climate volatility. Earlier the same evening, a storm in Pordenone, Italy, forced the cancellation of Riccardo Cocciante’s open-air concert after 4,000 spectators fled a sudden downpour, while in Cyprus the Windcraft Music Fest announced a July return to Katydata village with Balkan, jazz and experimental wind ensembles .
For Ljubljana, the night became a symbol of defiance: a decade of music forged in the rain.
