Seijiro Murayama was born in 1957 in Nagasaki, Japan. He has been working on improvisation since 1980.

He uses voice and percussion and tries to apply his practice of improvisation to other fields of creative activities. ​

​Graduated from Tokyo University of Foreign Studies. Eiichi Chino, Masahiro Nishie, Toshihiko Izutsu, Fumio Koizumi, Shuzo Kuki, then French Literature + Philosophy through skew reading, in particular, Blanchot. Their influence seems to have determined his activities’ direction since then.

​In 1982, he toured the United States with Keiji Haino, and during his stay in New York just after that, he encountered the radical, provoking music of John Zorn, a lower Manhattan emerging force. 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 publicly on an exploration of improvisation. Although he temporarily refrained from performing due to some 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 in the 90's.


In 99, he had an opportunity to live and work in France, which changed his way of thinking and playing, he began to concentrate in particular on solo improvisation.

​Today, he mainly performs in solo, duo and trio formats. As for collaborations with other fields' artists, he notes that even if he has experienced quite a lot of sorts of collaborations with dance and theater, his current interest is more towards words, images and sounds.
