Active in various disciplines of the contemporary field such as electroacoustic music, free improvisation, modern repertoire and collaborations with dance and theater, “Aresta” (edge) proposes to eliminate human presence of musical performance. An ensemble of saxophones becomes the interpreter and an autonomous instrument. Eight hanging saxophones of pyramidal metallic structures and a series of loudspeakers arranged inside the tubes act are the sound source, and the instrument, as a resonator body that amplifies and filters the sound, accommodates more than a hundred LED’s creating a great choreography that moves in perfect synchrony with sound.
