 European free jazz can generally be seen as approaching free improvisation, with an ever more distant relationship to jazz tradition.Specifically Brötzmann has had a significant impact on the free jazz players of the United States.A relatively active free jazz scene behind the iron curtain produced musicians like Janusz Muniak, Tomasz Stańko, Zbigniew Seifert, Vyacheslav Ganelin and Vladimir Tarasov.
