Question: Who did the composer of "Music for Electric Metronomes" study with?

<P0-S0>  He studied with Tomojiro Ikenouchi, Kishio Hirao, and John Cage. <P0-S1> Toshi Ichiyanagi (一柳 慧 , Ichiyanagi Toshi , born 4 February 1933) is a Japanese composer of avant-garde music. <SEP> <P1-S0>  The piece involves the manipulation of electric metronomes, followed by various unspecified sounds and actions. <P1-S1>  It is a very theatrical piece, and reflects Ichiyanagi's affiliation with Fluxus, an experimental art movement from the sixties. <P1-S2>  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. <P1-S3> 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. <P1-S4>  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. <P1-S5>  There is no conductor for the performance. <P1-S6>  It has been recorded on the album "Toshi Ichiyanagi: 1960's & 1990's". <P1-S7>  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> <P2-S0> Michael Nicolella (born December 31, 1963 in Providence, RI) is an American classical guitarist and composer. <P2-S1>  Described as an iconoclast, he is known for his versatile, adventurous and eclectic approach to repertoire, including the incorporation of electric guitar into his concert programs and recordings. <P2-S2>  Nicolella's repertoire ranges from the Baroque to the present. <P2-S3>  His most recent recording is his own arrangement of the complete cello suites of Johann Sebastian Bach; while his past four recordings focused on contemporary music, including his own compositions, alongside those of Toru Takemitsu, Elliott Carter, Luciano Berio, Hans Werner Henze and Steve Reich. <P2-S4>  He has championed music by such emerging composers as Laurence Crane and Jacob ter Veldhuis and has premiered many works written for him by other composers, including: Joshua Kohl, (of the Degenerate Art Ensemble), David Mesler, Christopher DeLaurenti and John Fitz Rogers, who in 2001 wrote the forty-five-minute piece "Transit" for Nicolella, scored for electric guitar and computer generated sound. <P2-S5>  His own compositions include works for solo guitar, chamber music with guitar, a classical guitar concerto ("Guitar Concerto"), and an electric guitar concerto ("Ten Years Passed"). <P2-S6>  His most recent major composition for soprano, guitar (electric and classical) and orchestra, "The Flame of the Blue Star of Twilight", was premiered by the Northwest Symphony Orchestra and soprano Alexandra Picard in April 2012. <P2-S7>  He has performed and collaborated with a wide range of groups and artists including: violinist Gil Shaham, rock singer Jon Anderson, best known for his work as lead vocalist in the progressive rock band Yes, broadway legends Bernadette Peters and Brian Stokes Mitchell, the Seattle Guitar Trio, jazz singer Johnaye Kendrick, classical music comedians Igudesman and Joo and is a frequent guest with the Seattle Symphony. <P2-S8>  Nicolella is a graduate of Yale University, Berklee College of Music and the Accademia Musicale Chigiana. <P2-S9>  He is currently based in Seattle, where he serves on the music faculty of Cornish College of the Arts. <P2-S10>  He is married to the painter Ann Gale. <SEP> <P3-S0> D. J. Sparr is an American composer and guitarist fluent in both classical and vernacular musical styles. <P3-S1>  He has performed with the Fondazione Arturo Toscanini, Eastman's "Musica Nova" Contemporary Music Ensemble, pop bands, and as a studio musician. <P3-S2>  D. J. premiered Michael Daugherty's electric guitar concerto with the Alabama Symphony in March, 2008. <P3-S3>  He was the classical guitar soloist for his own "Guitar Folio" with the University of Michigan Chamber Orchestra and recently performed Steve Reich's "Electric Counterpoint" to a packed house of over two-thousand at the Smithsonian Institution Hirshhorn Museum's "After Hours." <P3-S4>  He performs as a guest of Washington DC’s Great Noise Ensemble, which premiered his “General Electric”–a concerto grosso for rock band and chamber orchestra.
