The Musicians

CHRIS BURN ( piano, electronics, trumpets) UK

chris burnFollowing education at Surrey University where he studied composition with Reginald Smith Brindle, Sebastian Forbes and Robin Maconie, Chis Burn became involved in free improvisation and a commitment to this way of working has stayed with him throughout his career. He considers all his compositional work to be informed by his experiences in this area of contemporary music making. His group Ensemble, an octet of improvising musicians whose work embraces some aspects of composition has performed at many European festivals and broadcast on radio and television. He is also known for his performances of the piano music of Henry Cowell (writing a documentary for BBC Radio 3 about Cowell’s music in 1995), John Cage and other contemporary composers, sometimes including compositions and improvisations in the same concert.

LAWRENCE CASSERLEY ( electronics, sound processing )  UK

lawrence casserleyLawrence 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.
