'This is a powerful live recording without any arrangement by Japanese independent music icon Keiji Haino, who has been active in avant-garde activities straddling rock and free music in the underground realm since the 1970s, and Musqis, a performance group with an indefinite number of members led by multi-instrumentalist Hidenori Noguchi. Keiji Haino has been active since the 1970s, playing voice, guitar, hurdy-gurdy, polygonora, and various other instruments in solo performances and in bands such as Fushitsusha, Sanhedrin, Seijaku, and Nazoranai. In addition, he has performed with musicians from around the world, including Pan Sonic, Merzbow, and Peter Brotzmann, and is a unique musician who has always taken an independent stance in developing methods and forms of expression.

Musqis is an indefinite unit that started its activities around 2009~2010 by multiinstrumentalist Hidenori Noguchi. Its members have included Hajime Sawamoto, Tsubatics, Kazuhiro Aｒai, Tetsuya Anzai, Nei Ishikawa, Risa Takeda, Yuji Ishihara, and Satsuki Kameoka. They have also performed with Damo Suzuki, Tomokazu Ninomiya, and video artist Akiko Nakayama, and have been active mainly in live performances. This album "Keiji Haino + Musqis" is a recording of a live performance they performed together at Shinjuku JAM on October 9, 2017. Keiji Haino joined the band on voice and guitar, while Musqis consisted of Hidenori Noguchi (drums, electronics), Kentaro Nagata (guitar), Yuko Ando (saxophone), and Tsubatics (bass). The clash of sustained guitars and drums creates a heavy and free rock/improvised atmosphere, while the soprano sax and bass dance freely as if to expand the listener's vision.

The high-energy and noisy scenes that appear as if guided by Haino's voice are powerful listening points, but the freedom of the sound of the five members sometimes gives a sense of space as if the wind is blowing through, and the whole thing is attractive as a session that moves forward with a unique distance.' - yorosz(aka Shuta Hiraki)
