Maria W Horn is a composer hailing from the north of Sweden, based in Stockholm since 2011. She is interested in the manipulation of time and space through sonic extremes – oscillating between minimalist structures and piercing power electronics utilizing both digital and analog synthesis as well as acoustic instruments and audiovisual components. Her work examines aspects of human perception – how audiovisuality and overload/loss of perceptual stimuli can conspire to transcend everyday life and invoke alternate mental states. At Rewire 2021 she presents 'Dies Irae', a piece composed for female vocal quartet and electronics, premiered by Ensemble Format and recorded for Lumen Project in the Eric Ericsson hall in Stockholm, May 30th 2020. The piece is divided in two vocal parts followed by an improvisation for tuned glass, voice and electronics. For this edition of the performance the last part was joined by violinist Sara Parkman. Ensemble format consist of Paula Wegman, Vilma Ogenblad, Lisa Holmgren and Katarina Henryson.
