There is more than one artist with this name:
1. An onkyo experimental band from Japan
2. An American electronica/indie rock band from Detroit, Michigan. 1. Filament, consists of former Ground Zero members Otomo Yoshihide and Sachiko M, two of the defining artists of the onkyo music movement. In contrast to the dense, "chopped up", genre-hopping style of Ground Zero, Filament explores minimalist free-improvisation, concerned often with narrow-variations in tone and timbre usually without rhythmic structure or more than the slightest fragments of melody.
