I always have this mental image of a small, imaginary theatre. When I compose music, however, I dont think of the musicians bodies and their movements. I simply think of the music. I compose sound-gestures, not bodily gestures. - Georges Aperghis In accordance with his line of thinking, he sets sound gestures to music in his instrumental pieces, proceeding from linguistic units even in pieces which have absolutely no textual source. One might be able to describe his works for solo instruments as literally inventing a new sound language, as speaking music. This album is part of Klangforum Wiens Solo 5-CD series of recordings of pieces for one performer, which is the ensembles response to the 2020 Covid-19 pandemic.
