Question: when was the Japanese composer of avant-garde music who wrote Music for Electric Metronomes born 

Takanori Arisawa (有澤 孝紀 , Arisawa Takanori , April 2, 1951 – November 26, 2005) was a Japanese composer and arranger best known for composing the "Sailor Moon" anime series and "Digimon" series (Seasons 1-4).  He wrote music for the series, including its video games.  Born in Tokyo, Arisawa began to learn piano at the age of 20.  After graduating from Senzoku Gakuen College, Arisawa started his career in 1980 by composing "Shinjuku Transfer".  He worked for the Tokyo Broadcasting System and wrote several TV dramas. From the 1990s until his death, Arisawa began composing for anime series exclusively.  His work on "Sailor Moon" was initially based on pop music, but gradually began to change to those found in classical music.  "Sailor Moon" was successful and Arisawa won several awards for his work.  After "Sailor Moon", Arisawa composed music for several shows, including the "Digimon" series, until his death from bladder cancer in 2005. <SEP> Robert Gluck (born 1955) is a pianist and composer whose repertoire spans jazz, live electronic music, and avant-garde music.  Karl Ackermann (All About Jazz), wrote of the latest of Gluck’s five recordings: “As a composer and player, Gluck ranks with the likes of Andrew Hill and Cecil Taylor… Something Quiet is completely original, artistically spontaneous, and intellectually challenging.”  Allan Kozinn (New York Times) wrote that Gluck is “an accomplished jazz pianist” who played with “virtuosic fluidity.”  Keyboard magazine named him June 2009 “Unsigned Artist of the Month.”  Gluck’s current musical collaborators include saxophonists Joe Giardullo and Ras Moshe, bassists Christopher Dean Sullivan and Michael Bisio, drummer Dean Sharp, and computer musician/composer Neil Rolnick. <SEP>  The piece involves the manipulation of electric metronomes, followed by various unspecified sounds and actions.  It is a very theatrical piece, and reflects Ichiyanagi's affiliation with Fluxus, an experimental art movement from the sixties.  The only true scored "instrument" is an electric metronome for each individual player, though the varying sounds and/or actions may involve many different instruments and objects at the discretion of the performer.  Because the graphic notation of score (which is a series of dashes, lines, and numbers in an erratic pattern of connected paths) leaves a lot of room for personal interpretation and expression, each performance is unique, and almost certainly cannot be reproduced. Music for Electric Metronomes is an avant-garde aleatoric composition written in 1960 by Japanese composer Toshi Ichiyanagi for any number of performers between three and eight.  There is no conductor for the performance.  It has been recorded on the album "Toshi Ichiyanagi: 1960's & 1990's".  In a review of a performance by the S.E.M. Ensemble in 1992 at the Paula Cooper Gallery, the music critic of "The New York Times", Alex Ross, described the piece as "merely a timid, spastic prelude to György Ligeti's monumental "Poème symphonique" for 100 metronomes". <SEP>  He studied with Tomojiro Ikenouchi, Kishio Hirao, and John Cage. Toshi Ichiyanagi (一柳 慧 , Ichiyanagi Toshi , born 4 February 1933) is a Japanese composer of avant-garde music.
