KOORBAZEN. Fifty men. One voice. And an energy you won’t forget anytime soon.

KOORBAZEN (literally Choir Bosses) is not a traditional choir, but a male a cappella powerhouse of men aged 18 to 80. A colorful, close-knit group of civil servants, lawyers, students, entrepreneurs, conductors, fathers, sons, neighbors, and friends. What binds them? Curiosity, courage, and a shared love for music that moves, challenges, and surprises.

This contemporary choir sounds raw and pure. Of course, you’ll hear beautiful four-part harmony—but KOORBAZEN goes further. Much further. Spoken word, beatboxing, body percussion, and rap are seamlessly woven into powerful arrangements that venture far off the beaten path. Intimate moments alternate with explosive outbursts; from whisper-soft to full throttle. Every song is a story, every performance an experience.

What truly sets KOORBAZEN apart is the energy on stage. This is not just a group of singers, but a team that is greater than the sum of its parts. Men of different generations and backgrounds find one another through music and stories, and that connection is palpable all the way to the back of the hall. The dynamic arrangements are hurled into the world with heart, passion, and total commitment—straight into the audience’s core.

A KOORBAZEN performance leaves no one untouched. You feel the tension, the humor, the power, and the vulnerability. Women fall en masse for this imposing ensemble, and men leave the venue with just one thought: I want this too.

KOORBAZEN is not just a choir. It’s an experiment, an experience, a musical encounter that lingers. One thing is certain: once you’ve seen KOORBAZEN, you’re hooked.
