"Lawrence Casserley (born UK, 1941) has devoted his professional career, as composer, conductor and performer, to real time electroacoustic music. In 1967 he became one of the first students of Electronic Music at the Royal College of Music, London, UK, on the new course taught by Tristram Cary. Later he became Professor-in-Charge of Studios and Adviser for Electroacoustic Music at the RCM, before taking early retirement in 1995.

He is best known for his work in free improvised music, particularly real-time processing of other musicians' sound, and he has devised a special computer processing instrument for this work (picture above). He has worked with many of the finest improvisers, particularly Evan Parker, with whom he works frequently as a duo partner, in various larger groupings and in the Evan Parker Electro-Acoustic Ensemble. He also works as a soloist, processing sounds from voice, percussion and home-made instruments. CDs have been released by ECM, Konnex, Leo Records, Psi, Sargasso and Touch.

Much of Casserley's work has involved collaboration with other art forms, including poets, eg Bob Cobbing, and visual artists, including Colourscape artist Peter Jones. He is a Director of the Colourscape Music Festivals, presenting contemporary music in the unique environment of the Colourscape walk-in sculpture. He also collaborates with Peter Jones on sound/light installations.

Casserley's "instrumental" approach to live computer sound processing is the hallmark of his work; the Signal Processing Instrument allows him to use physical gestures to control the processing and to direct the morphology of the sounds. This is the culmination of forty years of experience in the performance of live electronic work; his earliest live electronic pieces were performed in 1969, and he has performed many of the live electronic "classics" of the 20th century; he has also collaborated with other composers to realise their electronic performance ideas. He is noted for the breadth and variety of his collaborations, which cross styles and generations."

"Jeffrey Morgan (born March 20, 1954) is an American jazz musician and composer. He has been heavily active in the fields of free jazz and improvised music.

Morgan started studying the Performing Arts: Music; Dance; Experimental Theater; Ethnomusicology; Philosophy of Aesthetics; and Eastern Religion at The Evergreen State College in Olympia, Washington in 1973. During his education he attended the legendary Creative Music Studio in Woodstock, NY, and studied under Karl Berger, Don Cherry, and Oliver Lake as part of his external studies program. Moreover, in 1976 he created his first compositional work for music and dance - Distress Mistress, and performed his first ensemble work, The Delirium Dimension.

In 1977 he created his first multi-media interdisciplinary work - Galactic Visions, a composition for music, dance, slide projectors, costumes, and light design. Over the next several years he conceptualized and composed a few collaborative interdisciplinary works, such as It's Only Money, C.A.S.H, Transient Landscapes; and Mykrocozm, wherein he also had directing and acting responsibilities. In 1982 Morgan co-founded Presto Chango, a musical theater/performance group that incorporated costumes and stage design along with Andrew Woodruff and Bob Heywood. Two years later together, along with Paul Hoskin, he co-founded the New Art Orchestra in Seattle, Washington. He also worked for Muzak as supervisor to re-evaluate their library of music.

In 1987, Morgan moved to Birmingham, Alabama and worked with dancers Mary Horn and Susan Hefner; he also started an ongoing collaboration with LaDonna Smith. In 1988, he made his first tour in Europe with the Seattle-based trio Clank together with Johnny Calcagno and Charly Rowen, as well as working with several international musicians from Denmark, England, Germany, and Czechoslovakia. Since 1991, he has resided in Cologne, Germany, remaining active in the field of jazz and improvised music. He has also engaged in collaborations with Alan Silva, Keith Rowe, Peter Kowald, Paul Lytton and Xu Feng Xia just to name a few.

From 1991 to 1996 he organized the Drang in Klang festival for experimental and improvised music, and in 1994 he established another open-door workshop for Conceptual Composition and Improvisation in Cologne, which led to invitations to lead other workshops in Bielefeld, Hamburg, Lisbon, Leeds and Wuppertal. Also, in 1994 he composed another interdisciplinary work entitled In the Shadow of the Gambler which was performed in Cologne and Krefeld. Moreover, he has led three classes through a group process focused on Installation and Performance: "Elements"; "Haunted House"; and "N-Station" respectively, at the Tekniske Skole in Copenhagen."
