Unsound Music Festival is a prominent brand that focuses on a diverse range of contemporary music, including emerging, experimental, and leftfield sounds that defy typical genre boundaries. Since its founding in 2003, Unsound has been influential in identifying innovative scenes and radical sounds, gaining a reputation for pushing boundaries.

The festival originally faced challenges, with its inaugural edition ending abruptly due to its avant-garde music choices. Now, Unsound hosts its main festival annually in Kraków, along with events in various international cities. In addition to showcasing emerging talent, Unsound commissions new shows, fosters cross-border collaborations, repurposes unique spaces for performances, and even has a fragrance project inspired by sound.

Moreover, Unsound functions as a platform for releasing new music and books. With a history of collaborations in the post-Soviet region and beyond, Unsound continues to be a trailblazer in the world of experimental music.
