Claudio Jacomucci: Vortex (2014) for 3 accordions by Claudio Jacomucci published on 2017-02-11T23:10:18Z Vortex was composed for Delaney’s dance to Quatermass-X video "Observations of the air of the wind of the earth and the celestial vault". A rotating dome of an old astronomical observatory is screened high on a Church interior. Its raw sound is reprised by the tones of three accordions positioned far from one another in the circular aisle. Such tones are shaped into dynamic impulses that suggest a counterclockwise spiral sound. Fábio Palma, Andrzej Grzybowski, Przemek Wojciechowski premiered the work.
