Signal Tide is a sound and extraterrestrial radio installation artwork by Kata Kovács and Tom O’Doherty. The work combines real-time signals from an abandoned satellite currently orbiting the earth (the LES-1, launched in 1965) with specially-commissioned music and sound, created by David Bryant (of Godspeed You! Black Emperor and Hiss Tracts), Drew Barnet, and James Hamilton, in collaboration with Kovács/O’Doherty.
Signal Tide was initially presented at Los Angeles County Museum of Art, from September 21.–24., 2017.
Research and development of the work was supported by the LACMA Art + Technology Lab.
