Amgen presents the historic recording of Éliane Radigue's »Asymptote Versatile« (1963–64), widely recognized as the oldest surviving composition by the pioneering French electronic music composer. This monumental work was performed for the very first time at the Huddersfield Contemporary Music Festival on November 26, 2023, marking a truly historic event as Radigue had resolutely refused permission for this work to be presented in concert — until now. The legendary composer referred to her 1960s works as »propositions sonores«, rather than compositions, and this piece is the only one she kept from that formative period. The graphic score comprises logarithmic curves devised from the Fibonacci sequence, superimposed over sheets of additional notation, to be performed as sustained tones by up to four groups of acoustic instrumentalists spanning the full range of the audible spectrum.
