Sun Rings is a Kronos Quartet project comprising pre-recorded sounds from space, images from space, music for string quartet and chorus composed by Terry Riley, and visuals by Willie Williams.[1] [2]
It premiered 26 October 2002 at the Hancher Auditorium, University of Iowa.
The project started in 2000 when the NASA Art Program invited the Kronos Quartet to incorporate sounds, recorded over a period of 40 years by plasma wave receivers on board spacecraft, into music.
