Polish Jazz Festival 2026 [KOSMONAUCI]

KOSMONAUCI – an electrifying young Polish quartet with a jazz background that draws on hip-hop, drum & bass and improvisation in its musical language. The instrumentation, which includes saxophone, bass, vibraphone and drums, creates the group’s unique style, balancing emotional melodies with polyrhythmic structures. This concert will transport the audience through galaxies of musical discovery – a journey worthy of their name (Cosmonauts).
21st March 2024 marked the release of Kosmonauci’s debut album Sorry, nie tu, released on U Jazz Me, a sublabel of U Know Me Records, as the imprint’s inaugural album. Notably, the entire vinyl pressing sold out in preorders even before the release. The sophomore record Brudna-Bielizna was released on 3rd April 2026 via the same label.
Kosmonauci have already performed at renowned Polish jazz festivals, including the Jazz Jantar Festival and the National Philharmonic in Warsaw, gaining acclaim from both audiences and critics. Since the release of their debut album, they have been touring Europe extensively. The last year was rich in festival appearances, including ESNS, MENT, Vinterjazz, Mladí ladí jazz, Europe Day, OFF Festival, BUSH, and Fira B!.
