Signal Tide — Two Passes: A Special Audio Mix by Kovács/O’Doherty

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. 
 

Signal Tide Companion — An Interview with the Artists

Joel Ferree from the LACMA Art + Tech Lab spoke with Kata Kovács and Tom O’Doherty about the inspiration behind Signal Tide, and the project's research and development. Included in the interview are anecdotes about tracking the signal of the LES-1 satellite from LACMA's rooftop, studying the folk music traditions of New England, recording the musical score, and more.

This mix is a collection of the recordings that were eventually incorporated into the generative score that accompanied the broadcast of the LES-1 signal in the Signal Tide performances at LACMA. Kata Kovács and Tom O’Doherty have worked as a collaborative duo since 2011. Their work combines elements of durational and time-based art, minimalist movement, and electroacoustic music and sound. This work often applies rigorous processes to simple but frequently-overlooked phenomena — they are interested in processes, sounds, and movements that come close to imperceptibility, and the ways in which this material can be transformed through repetition, patterning, layering, and archiving. They live and work in Berlin, Germany.
