From Kids to Being Twenty-Something: Kasi and Antonius in Vienna
After supporting Zartmann in Vienna at the beginning of this month, Kasi and Antonius returned to Austria's capital city on the 23rd of March for their "kids tour 2026", named after their new album kids, which had been released just three days prior to their Vienna show.
German singer CARLI opened the night at Flex, easily warming up the crowd with her signature blend of indie, pop, and rock. Fans particularly enjoyed her songs "PINOCCHIO" and "CARLI", which quickly built on the already lively atmosphere and heightened the audience's excitement. After her set, when the lights came back on and club songs like "Last Friday Night (T.G.I.F.)" were playing, she returned to the stage to pack up her microphone, casually singing along to the music and treating her fans to a spontaneous dancing session. After more songs from the 2000s and early 2010s were played, which perfectly fit with the new album's nostalgic theme of growing up and now being in your twenties, the lights eventually dimmed. The dark curtain with "kids kids kids kids" imperfectly written on it in white was then backlit, revealing only the outlines of the two artists behind it.
From the very first moment Kasi and Antonius and their band were revealed, the crowd went wild and started singing and screaming along to their songs, old and new alike. During a very intimate moment, both of them left the stage and came down into the crowd, a circle of fans in awe, surrounding them. There, they played acoustic versions of their new song "925" and of one of their most famous ones, "vielleicht in einem jahr". Back on stage, the crowd turned into an ocean of lights during the track "leicht beschwipst_demo2", as fans used their phone flashlights to fill the room with a soft glow. The more intimate atmosphere continued as other slow songs like "73" or the new track "Juli" by Antonius were played. The room was filled with people's focused gazes, as well as a thick haze, which added to the atmosphere as you couldn’t make out any faces and only saw the silhouettes of the artists on stage. This was especially prominent during a solo by their guitarist, during which you could even make out single hairs on the back of people‘s necks in the audience as they watched in admiration and curiosity.
Slowly picking up pace with another fan favourite, "Boys Do Cry", Kasi and Antonius transitioned into the more energetic part of their set. The party really started, however, when they performed "25grad", a track they wrote with 01099. Bathed in a warm yellow light, it felt like one of those warm and sunny days, spent outside with friends that could go on forever. Just like with not wanting such days to end, the crowd wasn't ready to let go of the night either. Even after two more songs from their new album, fans immediately began chanting „Zugabe!“ before the band even left the stage. Their calls were answered as Kasi and Antonius returned to engage the crowd once more, even getting everyone to turn off their phones during "meinen die uns", a collab with Zartmann and Aaron, known for its clear stance against the German right-wing party AFD. As Kasi explained, they don't make political music, but in times like these, it's important to be loud and stand for what you believe in.
The concert was closed with the last track from the album, "die welt geht vor die hunde", written last year in a Vienna studio on one of those scorching 40-degree days, as the two artists revealed. While sharing that he channels his feelings into music, Kasi encouraged his fans to seek help and to reach out to others, so they don't have to struggle alone. The night ended with him telling everyone to get home safely.

Usually you'll find me at a concert, somewhere between barricade and moshpit or of course behind my camera. I love not only documenting the energy on stage, but also capturing the little moments in between. Vienna based:)
