From Kovács/O’Doherty's 2016 Art + Technology Lab project, Signal Tide. The artists produced a series of experimental music performances featuring a call and response with a live satellite. The work was developed to be a poetic reply to the erratic signals of LES-1, a defunct spacecraft that ceased to function in 1967 but unexpectedly started transmitting again in 2013. Signal Tide was essentially a sound and extraterrestrial radio installation, which combined the satellite’s wavering signal overhead with a special generative musical score based on sacred harp singing melodies—a tradition of sacred choral music originating in New England.
