Kronos Quartet's new recording of Terry Riley's Sun Rings will be released by Nonesuch on August 30, and they have just released the official video, featuring Willie Williams's visual design for the staged multimedia production of the piece, of the 'Beebopterismo' movement.

Kronos have performed Riley's NASA-commissioned work dozens of times around the world but this is their first commercial recording of it. You can pre-order the recording here: https://smarturl.it/RileySunRings
