A Japanese rock band specialising in the psychedelic rock, space rock and noise rock genres. The band consists of electric guitarist and singer Keiji Haino, and a shifting cast of complementary musicians. The group released the majority of its material in the 1990s. The band's sound is influenced by German krautrock bands of the 1970s and British psychedelic music of the 1960s and 1970s. 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.
