Brudna - Bielizna is the second album by the boy band Kosmonauci. This album consists of original compositions by the band members, which were created over the past two years and evolved together with the artists during concerts. The Kosmonauts' music is rooted in jazz and improvisation, but over time, the musicians have developed many new paths and ways of drawing from many other, seemingly disparate musical genres. On the album Brudna - Bielizna the Kosmonauts continue to explore various genre and stylistic combinations. However, the second album is more focused and connected to the band members' jazz inspirations. Kosmonauci have been playing together since high school, and this is clearly audible.
