Seijiro Murayama (born 1957 in Nagasaki) is a percussionist and drummer. In 1982, he toured the United States with
Keiji Haino, and during his stay in New York immediately after that , he encountered the radical, provocating music of
John Zorn. After coming back to Japan, through the explosive sound trio Absolute Null Punkt, under the influence of Akira Aida, Kenichi Takeda, Masami Akita, the magazine Transonic, musicians
Derek Bailey, Kaoru Abe, etc., he embarked on an exploration of improvisation. Although he temporarily refrained from performing due to doubts about the styles of the first generation of improvisers he had followed, he restarted playing, thanks to the movements such as Onkyo in Japan, named by certain foreign critic in the 90's. In 99, he had the opportunity to live and work in France, that changed his way of thinking and playing, he began to concentrate in particular on solo improvisation, which had been a long-standing challenge. Today, he mainly performs in solo, duo and trio formats. As for collaborations with other fields' artists, he notes that even if he has experiences quite a lot of sorts of collaborations with dance and theater, his current interest is more towards words and images, but finally it depends on what kind of person the Other is.
