"Susan Alcorn (born 1953) is an American composer, improvisor, and pedal steel guitarist. Having started out playing guitar at the age of twelve, she quickly immersed herself in folk music, blues, and the pop music of the 1960s. A chance encounter with blues musician Muddy Waters steered her towards playing slide guitar. By the time she was twenty-one, she had immersed herself in the pedal steel guitar, playing in country and western swing bands in Texas.

Soon, she began to combine the techniques of country-western pedal steel with her own extended techniques to form a personal style influenced by free jazz, avant-garde classical music, Indian ragas, Indigenous traditions, and various folk musics of the world. By the early 1990s her music began to show an influence of the holistic and feminist "deep listening" philosophies of Pauline Oliveros.

Though mostly a solo performer, Alcorn has collaborated with numerous artists including Pauline Oliveros, Eugene Chadbourne, Peter Kowald, Chris Cutler, Joe Giardullo, Caroline Kraabel, Earl Howard, Le Quan Ninh, Sean Meehan, Joe McPhee, LaDonna Smith, Mike Cooper, Walter Daniels, Ellen Fullman, Jandek, George Burt, Janel Leppin, Michael Formanek, Ellery Eskelin, Fred Frith, Maggie Nicols, Evan Parker, Johanna Varner, Zane Campbell and Mary Halvorson."

"Terry Rusling (April 2, 1931 - November 27, 1974) was a Canadian electronic music composer, who used graphic notation. Some of his works were used to accompany radio and television broadcasts.

Terry Rusling worked as an engineer for the Canadian Broadcasting Corporation (CBC). He was on-air engineer for the Gilmour's Albums hosted by CBC broadcaster Clyde Gilmour. In the early 1960s, Morris Surdin, a composer working at the CBC, suggested to Rusling that he try out the electronic studio at University of Toronto, Faculty of Music (UTEMS). Through Surdin, Rusling was introduced to Dr. Myron Schaeffer, to whom he submitted his first electronic compositions. Schaeffer invited Rusling to attend the graduate seminar with Dr. Schaeffer at the University of Toronto, Faculty of Music, using the renowned electronic music studio (UTEMS) which included instruments designed by Hugh LeCaine such as the Special Purpose Tape Recorder. Rusling was awarded the title of Research Associate at the University of Toronto Faculty of Music. Among the notable composers who studied at University of Toronto's Electronic Music Studio (UTEMS) University of Toronto, Faculty of Music were John Mills-Cockell, Pauline Oliveros, Ann Southam, Gustav Ciamaga, John Beckwith, among others. After receiving a Canada Council he travelled to studios in the USA and Europe. He continued his studies and composed music in studios at the Psycho Acoustic Institute at Ghent University, Belgium; the University of Utrecht; and the University of Illinois. During this period he was also known to be the recipient of a Canada Council Grant in support of his travel, education and production of electronic music. He also did work at the University of Rochester with Wayne B. Barlow as well as in Paris where he studied with Pierre Schaeffer. He spent two months at the Phillips lab in Holland learning about their new electronic equipment. All of Terry's music was precisely notated using mathematics and other symbols. His music was often inspired by his interest in visual art. During this period Terry also reported on an interview on CBC Radio that he worked at the BBC Radiophonic. He specifically mentions Barry Burmage.

Several of his works, including The Trains, a piece of musique concrète, were broadcast on the CBC and he composed an electronic theme for the nightly news. One of his public performances at computer tape music was at the Bohemian Embassy in Yorkville, Toronto. October 1964. He also collaborated with visual artist Zbigniew Blazeje in a large multimedia exhibition in 1967 called Audio Kinetic Environment which began at the Art Gallery of Ontario and travelled to other galleries in Canada. The exhibit initially opened with music prepared by Blazeje. In an interview with Terry Rusling on CBC Radio, Rusling said that Blazeje approached him as he found the music he made was not good enough. Rusling stated he spent some time watching the kinetic installation and then proceeded to create a new score for the exhibition in Toronto and this music was used throughout the exhibits tour of Canada. The installation toured to other galleries including the Montreal Museum of Fine Arts. The music was set to trigger lights in the installation. There was also a radio program combining Rusling's music with Earle Birney's sound poetry on CBC Radio. After the piece was performed they discussed their personal approaches to their art forms. Birney discussed various approaches he took including sound poetry and using chance techniques, such as cutting phrases from newspapers including comics into bits of paper and finding combinations by chance. A related collaboration with poet Gwendolyn MacEwen, combining poetry with electronic music was also broadcast on CBC Radio. Rusling also worked with performance artist and sound poet Bob Cobbing and dancer Rima Brodie."
