Signal Tide is a sound and extraterrestrial radio installation artwork. It 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.

The work has a website with further details, audio, video, images, and downloads.

The research process for Signal Tide was supported by the Art + Technology Lab at LACMA, as one of the recipient projects of the Art + Technology Awards 2016.
