Toshi Ichiyanagi (一柳 慧 , Ichiyanagi Toshi , born 4 February 1933) is a Japanese composer of avant-garde music.
 He studied with Tomojiro Ikenouchi, Kishio Hirao, and John Cage.
Timothy Wesley John Brady (born 11 July 1956) is a Canadian composer, electric guitarist, improvising musician, concert producer, record producer and cultural activist.
 Working in the field of contemporary classical music, experimental music, and "musique actuelle", his compositions utilize a variety of styles from serialism to minimalism and often incorporate modern instruments such as electric guitars and other electroacoustic instruments.
 His music is marked by a synthesis of musical languages, having developed an ability to use elements of many musical styles while retaining a strong sense of personal expression.
 Some of his early recognized works are the 1982 orchestral pieces "Variants" and "Visions", his "Chamber Concerto" (1985), the chamber trio "...in the Wake..." (1985, 1988), and his song cycle "Revolutionary Songs" (1994).
Marco Oppedisano (born November 20, 1971 in Brooklyn, New York) is an American guitarist and composer whose compositions focus on the innovative use of electric guitar in the genre of electroacoustic music.
 His musique concrète/acousmatic music compositions have utilized multitrack recording and extended performance techniques for electric guitar, nylon string guitar and electric bass.
 In addition to musique concrète, compositions by Oppedisano also consist of "live" electric guitar in combination with a fixed playback of various electronic, acoustic (specifically female voice courtesy of Kimberly Fiedelman) and sampled sounds.
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.
 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.
 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".
Simon Leonardo P. Tan (born August 13, 1970) is a Filipino bassist.
 Beginning classical guitar lessons at age 13 at the Yamaha School of Music stimulated his later exposure to electric guitar and, inevitably, his interest in the electric bass.
 He studied the contrabass at the University of the Philippines College of Music from 1988 until 1992, then embarked on a professional musical career.
 His ability as a multi-genre bass player readily caught attention, notably in the pioneering Manila-based blues band, Lampano Alley, led by the Filipino blues singer and recording artist, Binky Lampano.
 This was followed by his tenure as bassist and composer with the award-winning Philippine jazz group, WDOUJI.
Torsten de Winkel (born January 6, 1965 in Frankfurt am Main) is a German musician, composer, and philosopher primarily active in the jazz, world music, fusion and electronic music genres.
 He is widely known as an electric and acoustic guitarist, but also records and performs on electric sitar, keyboards and various percussion instruments.
 Since the 1990s, he has initiated and participated in several platforms aimed at uniting the arts and sustainability issues.
Michael Nicolella (born December 31, 1963 in Providence, RI) is an American classical guitarist and composer.
 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.
 Nicolella's repertoire ranges from the Baroque to the present.
 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.
 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.
 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").
 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.
 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.

Morgan Sorne (born July 24, 1983), known in his solo music project as SORNE, is an American singer-songwriter, composer, multi-media artist, music producer, and actor based in Los Angeles, California.
 His musical style has been described tribal, electronica, avant-garde, avant pop, alternative rock, and electro-space-folk.

 His music utilizes layered vocal samples and unconventional (mostly hand-made) instrumentation.
