Although Otomo Yoshihide and Sachiko M had played as a duo before 1997, it was in that year they started playing duo often, as one of their major projects. In '97 and early '98, they called their duo A-102 as well as Filament, and occasionally called it simply "duo," with no specific name. Here, all of their duo concerts (sometimes with one or two guest musicians) from1997 to the present are listed, whether or not the name Filament was used.
