Yass is a term coined at the beginning of 1990s by Polish Avant-Garde Jazz musicians Tymon TymaĆski, Mazzoll and Tomasz GwinciĆski to describe the cross-genre, frequently arrhythmic, improvised music they played with e.g. MiĆoĆÄ, Ćoskot and Mazzoll & Arhythmic Perfection. Yass comprises the stylistics and elements of genres ranging from Folk to Punk Rock.
The Yass scene emerged in Tricity (an aggregate of the three neighbouring towns of GdaĆsk, Gdynia and Sopot) and Bydgoszcz whose MĂłzg became the "home venue" for Yass performers (e.g. Koncert w MĂłzgu) with its own label releasing a number of Yass productions.
A good overview of the Yass scene comes with the compilation album CaĆy ten Yass! released by Jazz Forum magazine just after the genre's heyday. .
