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.

Merzbow's sounds employ the use of distortion, feedback, and noises from synthesizers, machinery, and home-made noisemakers. While much of Merzbow's output is intensely harsh in character, Akita does occasionally make forays into ambient music. Vocals are employed sometimes, but never in a lyrical sense. Contrary to most harsh noise music, Akita also occasionally uses elements of melody and rhythm.  Akita's early work consisted of industrial noise music made from tape loops and conventional instruments. Similar to his present albums, he produced lengthy, disorienting pieces. He also became famous for the sheer volume of his releases.  The avant-garde nature of Akita's work made acceptance by mainstream and unprepared audiences difficult. When he performed with Kiyoshi Mizutani in 1988 at the Jazz-on-Amur festival in Khabarovsk, the Far East of USSR, his improvised, experimental electroacoustic set was praised by fellow musicians as well as the festival's producer. The number of the - jazz-oriented (and - even just curious) - crowd, however, had been expecting a more traditional (and much-much more quiet) performance, and started walking out. Prior to his second performance at the festival -- which was to be made to an even more conservative audience-- Akita was asked to play "more musically." On that first stage, Merzbow used the finest example of "classical analogue live noisemaiking technologies" to display: untuned guitar, a drumset, various micro-objects, small springs centered in its shell baffles, large aluminium boxes with strings inside to be attacked with a fiddlestick, etc. along with multi- piezo-pickuping and close-miking techniques, live processing through vintage US fuzz, ring modulator etc. boxes, and quite vivid and spontaneous approach, backed by domestically supplied slide and light shows. These live recordings were post-processed/re-mixed and released as Live in Khabarovsk, CCCP (I'm Proud by Rank of the Workers) LP - and as the (once more re-mixed comparing to the LP) CD 26 of the Merzbox later on.  During the 1990s Akita's work became much harsher and was generally mastered at a louder volume than usual. These were heavily influenced by death metal and grindcore bands of the time (a prime example is the Venereology album). The mid-1990s saw Akita being heavily influenced by psychedelic bands and this was reflected in various albums.
