The band consists of electric guitarist and singer Keiji Haino, and a shifting cast of complementary musicians.
After the departure of Shiraishi, Ayuo joined briefly in 1979 before Fushitsusha became a trio with the addition of Jun Hamano (bass) and Shuhei Takashima (drums).
Fushitsusha recently returned to duo status, with Haino supplementing percussion with tape loops, though the band is believed to have been on hiatus since 2001.
They are generally considered part of the Japanese psychedelic music scene alongside bands like Ghost and Acid Mothers Temple.
Their music occasionally ventures to the more aggressive "Japanoise" end of the sonic spectrum, but usually remains haunting and contemplative.
