One of the most adventurous composers and performers of the Italian avant-garde scene, member of the Gruppo di Improvvisazione Nuova Consonanza, great performer of the music of John Cage, Bertoncini started in the early ‘70s to design spectacular and visually fascinating “sound sculptures”, based on the aeolian sound principle.
Amongst his more spectacular installations: Vele, a massive aeolian harps (more than 7 meters high); Venti (winds), for 20 aeolian sound generators and 40 performers; and Chanson pour Instruments à Vent, an “assemblage” for aeolian harps, aeolian gongs, and one performer.
His self-built harps and gongs are excited by blows of compressed air, or by the composer’s own breath, and the resulting sound is amplified through contact microphones. If at superficial level they may sound like electronic music (long drones and swooshes of otherworldly sounds), at a close listening they reveal the intensity of a the pure and “mercurial” sound of air, far removed from any artificial or measurable principle. The CD presents the complete selection of his compositions for aeolian objects, from 1973 to more recent days.
