Keiji Haino, one of the foremost exponents of the Japanese avant-garde, always provides a masterclass in constantly shifting improvisation. John Butcher is a saxophonist of rare grace and power, who has expanded the vocabulary of the saxophone far beyond the conventions of jazz and other musics, to encompass a staggering range of multi-phonics, overtones, percussive sounds, and electronic feedback. Haino and Butcher met when Butcher opened for Fushitsusha at the show Cafe Oto arranged at St. John, Hackney -- five years ago. In 2016, they were invited to play two duo concerts -- at The Empty Gallery in Hong Kong and at Cafe Oto in London. Otoroku present the audio documentation of their first UK meeting. Recorded live at Cafe Oto in July 2016, the results are an uncompromising milieu of swirling sound played out as a total union of these two legendary performers. Hainos blues drenched guitar entices skittering notes from Butchers sax playing as numerous sonic clues unravel over the course of this unique and compelling journey. Personnel: Keiji Haino - vocal, guitars, etc.; John Butcher - saxophones and feedback. - Otoroku.
