Yass (music)

Yass (jass) is a Polish music style of avant-garde jazz which originated in the late 1980s, that mixes jazz, improvised music, punk rock, and folk. The style began with avant-garde jazz musicians from the Tricity and Bydgoszcz, where the jazz club Mózg became the unofficial 'home venue' for Yass performers, with its own label releasing a number of Yass productions. The term Yass was coined by bassist and guitarist Tymon Tymański, clarinetist Mazzoll and guitarist Tomasz Gwinciński, who wanted to stress the novelty of the new style. The first Yass album is generally regarded to be Tańce bydgoskie by Trytony.
