Eliane Radigue’s whole composing career has centred around one instrument, the ARP synthesiser. Now in her 87th year her focus has shifted to acoustic chamber and orchestral instruments. Her music is characterised by layering and blending sustained tones in pieces sometimes as long as two hours, in which she explores the way in which tiny alterations to timbre or pitch are perceived as dramatic changes to the music’s direction. She has always paid great attention to the arrangement of loudspeakers, and thus the listener’s spatial perception of her music, seeking to ensure that each individual listener has an optimum experience of the movement of sound around the listening space.
