Rytuał Dźwięku I Ciszy = The Rite Of Sound And Of Silence = La Rito De Sono Kaj De Silento = Das Ritual Des Tons Und Der Stille = Le Rite De Son Et De Silence

Released in 1988 under the Polskie Nagrania Muza label, Rytuał Dźwięku I Ciszy stands as a significant document of the Polish avant-garde and experimental music scene. Osjan, a collective known for their meditative, multi-instrumental approach that blended Eastern European folk traditions with jazz, ambient, and ethnic percussion, created this work during a period of shifting cultural landscapes in Poland. The album serves as an exploration of the interplay between sound and its absence, a hallmark of the group's philosophical approach to performance.

The album is noted for its multilingual title, a choice that reflects Osjan's efforts to reach a broad, international audience, incorporating Esperanto, English, German, French, and Polish. The composition highlights the group's signature instrumentation, featuring instruments such as flutes, gongs, and various percussion elements that favor texture and atmosphere over traditional melody. The design and presentation reflect the group's minimalist aesthetic, favoring an introspective listening experience that was characteristic of the experimental circles supported by state-distributed labels like Muza during the late 1980s.
