Masami Akita (Qiu Tian  Chang Mei , Akita Masami, born December 19, 1956), better known by his stage name Merzbow (merutsubau, Merutsubau), is a Japanese noise musician. He is best known for his style of harsh, confrontational noise exemplified on his 1996 release, Pulse Demon. Since 1980, he has released over 400 recordings, and has collaborated with various artists.

During the European tour in September-October 1989, Merzbow could only bring simple and portable gear; this led to the harsh noise style Merzbow became known for in the 1990s. Cloud Cock OO Grand (1990) was the first example of this new style, Merzbow's first digital recording (on DAT), and the first recording made for the CD format. It also includes live material recorded during the tour.  But when I started live in late 1980s I didn't like to use tape on stage. I like only live electronics. So, my studio works changed to more live composition style. I'm still using many tapes in studio works, but difference is I treat tapes and instruments. Before, I used tapes as overdubbing concept. But now tapes are crashing together, no static overdub. I found that style on Cloud Cock OO Grand.  Beginning in the mid-1990s, Merzbow began to be influenced by death metal and grindcore. Recordings from this time are mostly recorded at extreme volume, some mastered at levels far beyond standard (Noisembryo, Pulse Demon). In 1994, Akita acquired a vintage EMS synthesizer. From 1996, plans were made to release a "10 (or maybe 12)" CD box set on Extreme Records. In 2000, Extreme Records released the Merzbox, a fifty CD set of Merzbow records, twenty of them not previously released.  Throughout most of the 1990s, Merzbow live was a trio with Reiko A. on electronics and Bara on voice and dance. Masami Akita occasionally played drums for Hijokaidan during the early-mid 1990s.  In the early 1990s, Masami Akita composed the soundtracks to numerous kinbaku videos by Fuji Planning (Bu Er Qi Hua , Fuji Kikaku) and seppuku-themed videos by their sub-label Right Brain. Akita also directed Lost Paradise (Shi Le Yuan  Cheng Ma Fu Nu Fu Qie ri, Shitsurakuen: Jobafuku onna harakiri) for Right Brain. Some of this music was included on Music for Bondage Performance and Music for Bondage Performance 2, co-credited to Right Brain Audile. Director Ian Kerkhof would use a Merzbow track for his 1992 film La sequence des barres paralleles, and Akita composed original music for Kerhof's 1994 film The Dead Man 2: Return of the Dead Man. Kerkhof made the documentary Beyond Ultra Violence: Uneasy Listening by Merzbow in 1998. Akita also created music for Ilppo Pohjola's Asphalto (1998) and Routemaster (2000).  Since 1999, Akita has used computers in his recordings, having first acquired a Macintosh to work on art for the Merzbox. Also at this time he began referring to his home studio as "Bedroom, Tokyo". At live performances, Akita has produced noise music from either two laptop computers or combination of a laptop and analog synthesizers/guitar pedals. Reiko A. and Bara left Merzbow during this time, Reiko Azuma now has a solo career. Since 2001, Jenny Akita (nee Kawabata) started being credited for artwork on various releases.  Since 2001, Akita started utilising samples of animal sounds in various releases starting with Frog. Around 2002, Akita became a vegan, he stated how it began:  I started raising four bantams, the little ornamental chickens. With this experience as a start, I gradually started to be concerned and care about chickens and all the barn animals I used to eat without giving it a second thought before. So I started reading books and researching on the internet about Animal Rights and that triggered an awareness of "evil" that human society has done.  During this period, Akita also became a supporter of PETA which is reflected in his animal-themed releases. An example of this is Minazo Vol. 1 and Vol. 2, dedicated to an elephant seal he visited often at the zoo and Bloody Sea, a protest against Japanese whaling. He has also produced several works centered around recordings of his pet chickens (notably Animal Magnetism and Turmeric).  Also in 2002, Akita released Merzbeat, which was seen as a significant departure from his trademark abstract style in that it contains beat-oriented pieces. This has sparked some controversy among fans, though some reviewers pointed out that it sounded very similar to Aqua Necromancer (1998) which features samples of progressive rock drumming. Merzbird (2004) and Merzbuddha (2005) followed in a similar vein with sampled beats combined with Merzbow's signature harsh noise.  Starting in the mid-2000s, Masami Akita began to reintroduce junk metal and effects pedals back into his setup. By the early-2010s, he was using a large number of pedals, oscillators and tone generators, and reduced to a single laptop running granular synthesis software. In 2014, he toured without a laptop. In 2008, Akita reintroduced the drum kit, his first instrument. This can be heard on the 13 Japanese Birds series. At this time he changed the name of his home studio to Munemihouse.  Beginning in November 2009, Merzbow started releasing archival material from the 1980s and 1990s, both reissues and previously unreleased material, several of which were released on cassette. The Blossoming Noise label reissued the 1980s cassettes E-Study, Collection 004, Collection 005, Normal Music, and Flesh Metal Orgasm. The Kibbutz cassette was reissued on vinyl by Urashima. Other cassettes of unreleased material include Untitled Nov 1989, 9888A, April 1992, and Variations for Electric Fan. 2010-2013 saw the release several archival box sets; Merzbient, Merzphysics, Merzmorphosis, Lowest Music & Arts 1980-1983, and Duo.  Akita began collaborating with the Hungarian drummer Balazs Pandi in 2009, initially Pandi served as a live drummer for Merzbow. This resulted in the live albums Live at Fluc Wanne, Vienna 2010/05/18, Ducks: Live in NYC, and Katowice. Akita and Pandi then began to record studio albums collaborating with additional musicians, Cuts (2013) with the Swedish saxophone player Mats Gustafsson, Cuts of Guilt, Cuts Deeper (2015) with Gustafsson and Thurston Moore, and An Untroublesome Defencelessness with Keiji Haino (2016), all released by RareNoiseRecords. Akita, Pandi, and Gustafsson also toured together and released the live LP Live in Tabacka 13/04/12.  Merzbow also released several collaborations with industrial/noise musicians he had know since the 1980s: Spiral Right / Spiral Left with Z'EV, The Black Album with John Duncan, and a trio of releases with Maurizio Bianchi, Amniocentesi / Envoise 30 05 82 (a split with two tracks from 1982), Merzbow Meets M.B., and Amalgamelody. Gensho, the seventh collaborative releases with Boris, was released in 2016. It is a double album, one disc is by Boris and one by Merzbow, that are meant to be played at the same time.
