Exactly 60 years have passed since the legendary band Warsztat Muzyczny was founded in 1963 by Zygmunt Krauze. The group's goal was to organize concerts of avant-garde music. Four years later, in 1967, the band was finally composed of: clarinetist Czesław Pałkowski, trombonist Edmund Borowiak, pianist Zygmunt Krauze and cellist Witold Gałązka. The times have come when not only performers, but also listeners began to feel the need to experience new sounds. An innovative solution was the exploration of the sound possibilities of musical instruments, defined by the musicologist Józef Chomiński as the search for sonoristic properties (Latin: sonorus - sounding). The repertoire included on this CD focuses on composers who gave a clear impetus to the sonoristic tradition.
