Giacinto Scelsi is considered to be one of the most influential and at the same time one of the most enigmatic figures in 20th century avant-garde music. His work for solo cello is exemplary of his idea of "spherical sound" as the origin of every music. Marco Simonacci is a tireless fighter for the avant-garde of the 20th century and has already recorded works by Morton Feldman and John Cage for Brilliant Classics.
