Japan's first free jazz musicians included drummer Masahiko Togashi, guitarist Masayuki Takayanagi, pianists Yosuke Yamashita and Masahiko Satoh, saxophonist Kaoru Abe, bassist Motoharu Yoshizawa, and trumpeter Itaru Oki. A relatively active free jazz scene behind the iron curtain produced musicians like Janusz Muniak, Tomasz Stańko, Zbigniew Seifert, Vyacheslav Ganelin and Vladimir Tarasov. Some international jazz musicians have come to North America and become immersed in free jazz, most notably Ivo Perelman from Brazil and Gato Barbieri of Argentina (this influence is more evident in Barbieri's early work).
