Filament is a musical group from Japan that consists of Otomo Yoshihide and Sachiko M, two of the major exponents of the electroacoustic improvisation[1] style of music.
The two played as a duo for the first time on November 5, 1995 [2] in London, but it was not until 1997 that they began to play often together and Filament became one of their main projects.
At first their work together was branded as A-102, then they used both Filament and A-102, and occasionally simply "duo," with no specific project name.
Since their United States and France concert tour of May 1998, they have used the name Filament exclusively.
