In honor of groundbreaking American composer Terry Riley's 80th birthday, Nonesuch Records releases a new disc - 'Sunrise of the Planetary Dream Collector.' Riley and Kronos met more than 35 years ago, and since then, the quartet has commissioned 27 works from him, more than from any other composer in the group's history.

'Sunrise of the Planetary Dream Collector' includes a new recording of the title piece, which was Riley's first for Kronos, as well as previously unreleased recordings of Lacrymosa – Remembering Kevin and One Earth, One People, One Love from Sun Rings; Cry of a Lady (originally released on A Thousand Thoughts); and G Song and Cadenza on the Night Plain (both originally released on 25 Years).

Kronos' violinist, founder, and artistic director David Harrington says of the Quartet's remarkably fruitful relationship with Terry Riley, which began in the late 1970s at Mills College in Oakland, California: "There is no other composer who has added so many new musical words to our vocabulary, words from so many corners of the musical world."
